Ahti-Veikko Pietarinen Professor & Head of Chair in Philosophy Ragnar Nurkse School of Innovation and Governance Tallinn University of Technology ahti-veikko.pietarinen@helsinki.fi Fall 2013 1 Methodology and epistemology of Science: What is scientific method? What counts as scientific knowledge? Does science discover truths? Are its discoveries certain? How to choose between competing theories? What is the relationship between theories, hypotheses, evidence and experiments? Metaphysics of Science: Are all events, scientific phenomena etc. determined by causes? What is a scientific law? Is there a purpose in nature? Can other theories be reduced to some others (e.g., to physics)? Are some theories more fundamental than others? 2 What does technology mean? What is its relation to science? Can technology be defined? (Knowledge + material + organisation + product?) Can science be divided into ’pure’ and ’applied’ parts? How did technologies emerge? Do technologies necessarily grow out of scientific discoveries? Do some characteristics typify Western technologies? What were/are the impacts of technology to nature, environment, society, culture, politics, our long-term future...? 3 ”Everything that can be invented has been invented.” –The U.S. Office of Patents, 1899 ”The phonograph is not of any commercial value.” – T. A. Edison, c.1880 ”Heavier than air flying machines are impossible.” – Lord Kelvin, c.1895 ”The horse is here to stay, but the automobile is only a novelty-a fad.” – President of the Michigan Bank, advicing Henry Ford’s lawyer not to invest in the Ford Motor Company, 1903. ”I think there is a world market for about five computers.” –T. J. Watson, Chairman of the Board for IBM, 1943 ”There is no reason for any individual to have a computer in their home.” –President of Digital Equipment Corporation, World Future Society Conference, 1977 ”By 1980 all power is likely to be costless”. –H. Luce, founder of Time and Fortune magazines, 1956 Is quite a different bag of issues to a scientist, engineer, business executive, politician, attorney, reporter, artist,... Not just hardware or inventions Technology is knowledge, expertise, ’soft tech’, solutions & services Some attempted definitions (Misa 2009, p.8-, in Companion): 1. ”Things that fulfill our needs and desires or perform certain functions” 2. ”Application of understanding of natural laws to the solution of practical problems” 3. ”Information concerning processes and design” 4. ”Information needed to achieve a certain production outcome” 6 Not merely a socially neutral production factor knowledge – technique – organisation – product Knowledge transfer crucial to meaningful technology Knowledge is explicit and implicit/tacit; depends on truths, beliefs, desires, goals,...) Technology is contextual 7 Science (scientia) ”natural philosophy” until at least the modern period; ”natural sciences” emerged only later The Scientific Revolution (~1500-1700) ”Scientific method” properly articulated only in late 19th century – but inseparable from the entire history of science The term ”scientist” relatively new (Whewell, 1833) For Aristotle, science was the study of drawing inferences, given the premisses that are known (syllogism & deduction; induction) Reason, argument and experiment have always been important... 8 1. Suppose (as Aristotle believed) that the heavier a body is, the faster it falls to the ground and suppose we have two bodies, a heavy one called M and a light one called m. Under our initial assumption M will fall faster than m. Now suppose that M and m are joined together thus M+m. Now what happens? Well M+m is heavier than M so by our initial assumption it should fall faster than M alone. But in the joined body M+m, m and M will each tend to fall just as fast as before they were joined, so m will act as a ‘brake’ on M and M+m will fall slower than M alone. Hence it follows from our initial assumption that M+m will fall both faster and slower than M alone. Since this is absurd our initial assumption must be false. 9 2. Either there is a Christian God or there isn’t. Suppose you believe in His existence and live a Christian life. Then, if He does exist you will enjoy eternal bliss and if He doesn’t exist you will lose very little. But suppose you don’t believe in His existence and don’t live a Christian life. If He doesn’t exist you will lose nothing, but if He does exist you will suffer eternal damnation! ! So it is rational and prudent to believe in God’s existence and to live a Christian life. 1. 2.

Therefore, Drink driving is safer than either drinking or driving alone. Nothing is better than freedom. On the other hand, Prison life is better than nothing. Therefore, Prison life is better than freedom. To build a large thing, you need a plan. To make a plan, you need a written language. Neolithic British had no written language.

Does technology develop autonomously? Is it a key factor for societal and cultural developments? 17 How we form conceptions To acquire information we need reasoning, a way to move from what we know to something not yet known The formation and fixation of beliefs (conceptions) is interaction between two states of mind, doubt and belief Mind responds to the irritation caused by the action of thought, which gives rise to doubt. Doubt stimulates inquiry (research) until its cessation by forming a conception. How we revise beliefs 1. 2. 3. 4. Method of Tenacity (We don’t! Just live a happy life...) Method of Authority (Institutionalised revision) a priori –method (Revise according to what is ’reasonable’) The Scientific Method. 18 1. 2. 3. 4. 5. 6. Fallibilism: Most of our ideas are likely to turn out false, but we cannot be absolutely sure of any one of those that are not. The Final Opinion: Science can reach truth as the final belief agreed upon by all scientists. ‘In the Long Run’: If inquiry were to be pursued indefinitely long, then the final opinion would be reached. Scientific Attitude: No sham reasoning, fake reasoning. Structure of Scientific Inquiry: Abduction, deduction, induction. The Economy of Research: Prefer simple, explanatory and productive hypotheses. 19 1. 2. 3. Deduction: M is P S is M S is (necessarily) P Induction: S1, S2, S3,... are M S1, S2, S3,... are P Any M is (probably) P Abduction: M is P1, P2, P3,... S is P1, P2, P3,... S is (plausibly) M All the beans in this bag are white These beans in my hand are from this bag These beans in my hand are white. These beans in my hand are from this bag These beans in my hand are white All the beans in this bag are white. All the beans in this bag are white These beans in my hand are white These beans in my hand are from this bag. 20 1. 2. 3. The surprising fact, C, is observed But if A were true, C would be a matter of course Hence, there is reason to suspect that A is true. Abduction seeks a hypothesis to account for facts by guessing “Oftenest even a well-prepared mind guesses wrong. But the modicum of success of our guesses far exceeds that of random luck, and seems born of attunement to nature by instincts developed or inherent, especially insofar as best guesses are optimally plausible and simple in the sense of the ‘facile and natural’, as by Galileo’s natural light of reason.” (Peirce) 21 “There are a lot of facts to be known in order to be a professional anything — lawyer, doctor, engineer, accountant, teacher. But with science there is one important difference. The facts serve mainly to access the ignorance… Scientists don’t concentrate on what they know, which is considerable but minuscule, but rather on what they don’t know…. Science traffics in ignorance, cultivates it, and is driven by it. Mucking about in the unknown is an adventure; doing it for a living is something most scientists consider a privilege.” “Working scientists don’t get bogged down in the factual swamp because they don’t care all that much for facts. It’s not that they discount or ignore them, but rather that they don’t see them as an end in themselves. They don’t stop at the facts; they begin there, right beyond the facts, where the facts run out. Facts are selected, by a process that is a kind of controlled neglect, for the questions they create, for the ignorance they point to.” “Being a scientist requires having faith in uncertainty, finding pleasure in mystery, and learning to cultivate doubt. There is no surer way to screw up an experiment than to be certain of its outcome.” “We must teach students how to think in questions, how to manage ignorance.” Hypothetico-Deductive Model of Science 24 Often expressed as the process by which scientists decide, based on observations and experiments, that some theory, principle or law is true (”All A’s are B’s”). The Problem of Induction How to generalise from finite information? Is it a threat to scientific knowledge (scepticism)? Possible reply: Falsificationism (Sir Karl Popper) Science does not in fact rest on induction First: come up with a hypothesis or a theory, and then see if it stands up to a test: ▪ If tests prove negative, theory is falsified ▪ If tests fit the theory, continue to uphold it as undefeated. Scientific inference is refutation: Some A is not B → not: All A’s are B’s. 25 1. Some questions about falsificationism: If scientific theories are conjectural hypotheses that cannot be proved by observation and evidence, what makes science better or more trustworthy than, say, superstition or religious beliefs? Popper: Theories are falsifiable: ▪ They are formulated in precise terms, give definite predictions ▪ In contrast, nothing can refute something like astrology or folk beliefs. Falsifiability distinguishes science from non-science (Popper’s answer to the problem of demarcation): ▪ In science you should be able to say beforehand, what observational discoveries would make you to change your mind about your theory if such evidence were to arise in the future (fallibilism: we might be mistaken about out knowledge ’one by one’, but no scepticism follows) ▪ If no possible, conceivable observation can adjust our thinking, we are not doing science but are dogmatists about our beliefs. 26 Falsificationism does not solve (it rather evades) the ’problem of induction’ 2. What shows that a scientific theory is right? What is the rational basis for believing that the predictions that a theory makes are right? What is the role of past evidence? We don’t believe in new theories immediately, they start out as hypotheses. Do we need to try to solve it? Yes: Bayesianism 1. ▪ ▪ 2. Beliefs come in degrees in which we take something to be probable (these tend to be subjective probabilities) Pr( E / H ) Pr( H / E) Pr( H) (Bayes Formula) Pr( E) No: Induction is a natural form of reasoning – accept abduction and induction as the facts of the power of the mind to perform such feats. Amounts to rational belief revision Why do rational thinkers expect future to be like the past? 27 ”Day by day, nothing seems to change. But soon, everything’s different.” 28 Science is all about exploiting uncertainties 1. Improve the payoff, not knowledge (‘High risk-high gain’; research is a fat tail phenomenon) ▪ ▪ ▪ ▪ ‘Cheap’ science should be funded first Reduce the cost per testing a hypothesis (fallibilism → minimizing the losses) Higher expected return from a series of small trials than from a large single trial (non-linearity, convexity) Simplicity counts “How to take the step from stone axe to hand axe...” 2. Get rid of restrictive planning Need for exit strategies Follow the unforeseen; stretch your mental models, invent new concepts Centralized decisions tend to fail Lots of attempts needed before success (Angry Birds was Rovio’s 56th game) Invest on people, not on procuring ‘strategies’ or ‘research plans’ 3. Theory/science not a necessary condition for practical/technological development 4. “telling (angry) birds how to fly” Knowing well what doesn’t work The dilemma of “positive bias”: where to publish the negative results? “How not to become successful in life” “How I failed to make my first million” Theorem: Reductio ad absurdum (RAA) is not a good method of proof. Proof: by Reductio ad absurdum. 1. Suppose RAA were a good method of proof. 2. Then this argument would be good. 3. But this argument is no good. Therefore, RAA is not a good method of proof. http://consc.net/misc/proofs.html http://www.youtube.com/watch?v=Y4yBvvGi_2A http://inquiry.mcdaniel.edu/videos/CrossfireIntelligentDesign.swf http://web.maths.unsw.edu.au/~jim/worst.html 33 “10 Unsolved Mysteries”, Scientific American 10/2011 1.

Perhaps technology is older than science Science has become ”instrumentally embodied”, instruments are not merely tools but parts of the the theories & necessary conditions for the experiments & influencing the interpretations Maybe science has no ”foundations” – but – this need not imply recourse to the ’postmodern’ Now: Sociology of Science (STS, social constructionism) vs. practice-oriented Philosophy of Science Hacking, Ian (1983). Representing and Intervening (Cambridge UP); (2000)The Social Construction of What? (Harvard UP) 35 36 “Anyone who believes that the laws of physics are mere social conventions is invited to try transgressing those conventions from the windows of my apartment. I live on the 21st floor.” Alan Sokal, 1996: ”Transgressing the Boundaries: Toward the Transformative Hermeneutics of Quantum Gravity”, Social Text. The point was not only to show problems with the journal’s peer review practices, but to defend the standards of scientific & philosophical work from the threats of “postmodern literary intellectuals pontificating on science and its philosophy and making a complete bungle of both.” Check out Sokal’s new book: Beyond the Hoax: Science, Philosophy and Culture, Oxford University Press, 2009. Explains the original ’joke’ sentence by sentence Contains an ”Afterword” that was rejected by the Social Text “on the grounds that it did not meet their intellectual standards”. 37 How do we know about unobservable things? (Electromagnetic waves, viruses, electrons, quarks,...) Realists take observable facts sufficient to indirectly infer the existence of unobservable things. 1. In addition to making predictions, theories explain phenomena ’No miracles’-argument: realism the only philosophy that doesn’t make progress of science a miracle. Instrumentalists take theories about unobservables to be useful tools for computation and prediction but not about truth. 2. Scientists postulate all kinds of things but need not believe in them. ’Pessimistic meta-induction’: most past theories turned out false – why should I believe science at all? 38 39 The philosophical basis of the ‘interplay model’: 1. External influences on a practice are results of the interaction between practices. This interaction is seldom a one-way influence; the practices involved are changed in the interaction. 2. There are no hierarchically dominant practices in a strict sense. 3. Innovation in practices does not derive from scientific discovery, as it were in a linear sequence. (Gremmen 2009, in Companion, p.76) 40 “The world is full of wonderful products and services that occasionally disappoint and even harm us. This book explores the reasons these failures occur, examining them from technological, human, and organizational perspectives. Using more than 40 recent catastrophic events to illustrate its points, the book discusses structural and machine failure, but also the often-overlooked failure of people and of systems related to information technology, healthcare, and security. Faulty technology played a surprisingly small part in many of the scrutinized disasters, but cognitive factors and organizational dynamics, including ethics, are major contributors to most unexpected and catastrophic failures.” 41 Governments, large companies, science policy units, all interested in: How to make technological advancements? What research to support? Which methods can secure scientific & technological progress? But: Is technology product of applying science in problem-solving contexts? Is there a direct pattern from basic reseach to successful introduction and solving of practical issues? 42 43 Technical inventions seem to be products of a variety of circumstances Not directly dependent on the ’truth’ of scientific theories Selection processes for introducing new technologies not based on purely technical success (need consider manufacturing, economic, marketing, consumerist, social, ethical & legal factors) Markets behave irrationally Unintended consequences Technological change not an instrumentally rational procedure Technologies not value-free artefacts ’Science, Technology & Society’ interdisciplinary studies involving historians, economists, sociologists, engineers, philosophers,... 44 Substantive view sees technologies as autonomous cultural forces How cultures and humans change is more significant than the ostesible goals of technology (’the instrumentalisation of things has become the instrumentalisation of man’) Governments & development agencies wrongly believe that the lack of development/innovation is due to lack of resources to acquire/create technologies The problem is technology transfer Innovations cannot be forced, need seredipity, unplanning The way to advance technology is not only to advance science as such, but to deepen our understanding of the contexts into which techniques are introduced 45 Technology is not ”applied sciences”: Modern science & technology mutually interdependent (the interplay model) (telescopes, microscopes, steam engines… no immediate scientific concern) Premodern and modern techniques and practices define the inquiry Practitioners ”know how” something works in the context of the products Pragmatism (Peirce, Dewey, James): Action, practice, productiveness precedes the theoretical Technology is an activity, it cannot be exported (Dewey) There is nothing ’essential’ about technology The meaning is in the consequences, not in the things 46 Engineering science vs. ’ordinary’ science? 1. ’make things work’ vs. ’seek for the truth’ ? ▪ Pragmatism: truth is what ’works’; what has pragmatic, practical, experiental effects (importance of modelling, design) 2. Study the nature and behaviour of human products (artifacts) vs. study the natural phenomena? ▪ Determinism/naturalism: also human products are natural, governed by laws ▪ Constructivism/critical theories: also ’natural’ phenomena is a human product 47 The nature of artifacts 1. Homo faber: Artifacts depend on human manipulation; contrast with objects of nature Abiotic – or not? ▪ Domestication; GM; Bioinformatics; Nanotechnology Materiality? Usability? Artifact only if its ”author accepts it as satisfying some sortal description [for technological artifacts: ”material means y to achieve practical end x”] included in his productive intention” (Hilpinen 2004) Unintended by-products are not artifacts but artifices (”scrap”) Artifacts → Tools → Instruments (Dipert 1993) ”Artifacts are intentionally modified tools whose properties were intended by an agent to be recognised at a later time as having been modified for some use.” 48 49 2. Knowledge of artifacts in technology Descriptive knowledge of the science of the behaviour of artifacts (e.g., laws of analytic mechanics governing snooker balls) Normative knowledge of the use and application of artifacts (”These tools are good for X”) – the design aspect → The descriptive knowledge of science becomes transformed into something inventional 50 Engineering design “is the process of devising a system, component, or process to meet desired needs. It is a decision-making process (often iterative), in which the basic science and mathematics and engineering sciences are applied to convert resources optimally to meet a stated objective.” (Accreditation Board for Engineering and Technology, ABET) Conversion from functions to structures – but exactly how? Use science & reasoning from means to ends; or maybe like abduction? Not only instrumental task but social, economic, political,... How to bring in the environment (the know-how transfer)? How to measure the success of the design? The list of criteria may change during the design process ,or be part of it. 51 52 53 54 55 56 An expert is a man who has made all the mistakes which can be made in a very narrow field.” – Niels Bohr Design is a creative process How to create new possibilities (means) for new technical artifacts How many? How to select among them those to develop? Engineering knowledge involves: Basic design concepts (fundamental components); criteria & specs; theoretical tools (computation); quantitative data; practical/economic considerations; design instruments (Vincenti 1990). Faulkner (1994): knowledge of the world; of design practices; of the system of R&D; of final products; and of finding something new (innovations). In contrast to science, many of these involve prescriptive & normative kinds of knowledge And the major failures are typically caused by design failures... http://engineeringfailures.org/ 57 Life: Information processes and neg-entropy Self-sustainability, growth, replication, adaptation Communication, signalling 58 What have been the major contributions to the rapid socioeconomic development in the West?

The Maastricht Treaty: “The absence of certainties, given the current state of scientific and technological knowledge, must not delay the adoption of effective and proportionate preventive measures aimed at forestalling a risk of grave and irreversible damage to the environment at an economically acceptable cost.” Principle 15 of the 1992 Rio Declaration: “Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.” 66 Implications: 1. to understand it we need to understand the nature of (i) potential for irreversible harm (‘risks’) and (ii) scientific uncertainties 2. is a normative principle (favours environmental and human health factors over others) 3. refers to reasons for action, is not a guide or a recipe for what action to take 4. applies in all contexts (technology, policy making, governance, international law, trade,…) 67 Risk analysis and technological assessment Basic problem: the lack of knowledge about the effects of technology Too often treated separately What is risk? 1. 2. 3. Something unwelcome may or may not occur: “Smoking is a big health risk” Probability of unwelcome event: (decision-making under uncertainty or under risk, gambling): “How likely it is that an expensive treatment will fail” Severity measure (expectation value) obtained by multiplying the probability of unwelcome event with a measure of its disvalue (risk analysis): “Is nuclear energy ‘better’ than fossil fuels” Risk: there is something we know about what we do not know 68 The classical distinction between risk and uncertainty (Keynes 1907): ”Risk is measurable uncertainty”. Given any two alternative events, A and B, and given the evidence (conditional probabilities), either • A is more likely/probable than B • B is more likely/probable A • A and B are equi-probable, or • A and B are incomparable (= uncertainty). The problem of uncertainty concerns the mixture of the inferential and the representational aspects of events and abilities. Either there is a Christian God or there isn’t. Suppose you believe in His existence and live a Christian life. Then, if He does exist you will enjoy eternal bliss and if He doesn’t exist you will lose very little. But suppose you don’t believe in His existence and don’t live a Christian life. If He doesn’t exist you will lose nothing, but if He does exist you will suffer eternal damnation! So it is rational and prudent to believe in God’s existence and to live a Christian life. Or is it? 70 ”I will never marry again.” –Barbara Hutton, after her 2nd divorce, 1941 ”I will never marry again.” –Barbara Hutton, after 3rd divorce, 1945 ”This is positively my final marriage.” –Barbara Hutton, after marrying her 6th husband, 1955 ”He has all my previous husbands’ best qualities and none of the bad qualities.” –Barbara Hutton, after marrying her 7th husband (Prince of Vietnam), 1964 (In 1966, she filed for divorce.) Risk (something undesirable) ≠ uncertainty (value-free) Risks are both fact- and value-laden (objective and subjective) “Landmines tend to mutilate” Are our daily risks getting higher or lower? Life expectancy is growing, but on the other hand there are new possibilities of large-scale global risks Is technology assessment an optimisation problem? In new and emerging technology assessment (such as in NBIC-technologies), risk analysis happens under fundamental uncertainty: we do not even know the possible effects, let alone their probabilities (the ‘tuxedo fallacy’) 72 The Tuxedo Fallacy “There are known knowns; there ← Instrumental rationality; are things we know we know. optimization; min-max principle We also know there are known unknowns; that is to say, we know ← Instrumental rationality; risk there are some things we do not analysis; conditional probabilities know. But there are also unknown unknowns – the ones we ← Procedural rationality; no don’t know we don’t know.” risk; no probabilities – D.

Post-/Trans-humanism, superintelligence Singularity Hypothesis • The simulation argument: either • 1. nearly all human-level civilizations go extinct before becoming posthuman, or 2. any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history, or 3. we are almost certainly living in a computer simulation (Boström 2009) Find errors in this argument!
