15.1 (A Muddy Paste?)

-> We’ve now covered nearly a century of argument about science, now we’re connecting three main ideas

  1. Empricism

  2. Naturalism

  3. Scientific realism

But there are conflicts between them, or between pairs of them

  • For example, scientific realism requires being opposed to some central ideas in the empiricist tradition


15.2 (The Apparent Tensions)

To summarize:

  • Empiricism says the only source of (scientific) knowledge is experience

  • Naturalism says that the only way to resolve philosophical problems is by approaching them within a scientific picture of ourselves and our place in the universe.

  • Scientific realism says that even the unobservable structures of the world can be be described by science

Where Many of the Problems Come From

-> Empiricism is the source of many problems

  • Extreme empiricism: It doesn’t even make sense to talk or think about what might lie beyond experience

  • Moderate empiricism: It’s hard to see how experience itself can support a hypothesis about structures lying behind experience

The Undetermination of the Theory of Evidence

-> Empiricism vs Scientific Realists

Empiricists:

There’ll always be a range of alternative theories compatible with all of our evidence, so it’s not possible to have empirical grounds for choosing one over the other and saying it represents how the world really is. If we have no empirical grounds for that kind of choice, then we have no grounds at all.

Empiricism vs Naturalism

Empiricists often use a foundationalist structure, and say that we start from a starting point where we only have direct access to our ideas and experiences, working out from there. Naturalism is opposed to the idea of starting within the circle and then working your way out.

The Sociologist Argument:
Empiricist tradition in philosophy is a collection of myths.

  • In actual science, experience isn’t the arbiter of theoretical disputes

Naturalism vs Scientific Realism

-> Naturalism requires a form of scientific realism

The Sociologist Argument:
We must abandon the philosophical myths about science’s contact with reality.


15.3 (Empiricism Reformed)

-> Godfrey-Smith’s take

Two-part argument:

  1. A general philosophical discussion regarding epistemology

  2. Empiricism as a view about science

Epistemology in General

It’s wrong to think of two layers or domains in the world:

  • One which is accessible to us and familiar - the domain of experiences a.k.a. domain of the observable.

  • The other inaccessible, mysterious, ‘theoretical’ and problematic.

The Right way to Describe the Role of Experience

  • We are biological systems embedded in a world containing objects of all sizes and at all different kinds of distance and remove from us.

  • Our mechanisms of perception and action give us a variety of different kinds of contact wth these objects.

  • Our ‘access’ to the world via thought and theory is really a complicated kind of causal interaction which is constantly being expanded, as our technology improves

  • Parts of the world that at one time were the subject of speculative inferences are now much more directly observed and evaluated.

To solve the ‘undetermination’ argument, you learn what kind of reliability you have in your attempts to know about the world.

  • You can apply the same approach to inferences and modeling strategies in science by asking:

What sort of reliability are we able to achieve sing different sorts of scientific reasoning and model-building strategies?

Over time what was once inaccessible and only ambiguously model-able has now become routinely accessible and observable. (e.g. DNA)

  • You can meta-analyze how well you did after those things become accessible and routine to help you do better in the future

The Strategy of Science

-> Science is the strategy of subjecting even the biggest theoretical ideas, questions, and disputes to testing by means of observation.

The strategy is to attempt to assess big ideas by exposing them to experience.

The Scientific Strategy is:

  1. To construe ideas

  2. To embed those ideas in surrounding frameworks

  3. To develop those ideas in such a way that exposure to experience is sought even in the case of the most general and ambitious hypotheses about the universe

The Sociology of Science

-> We need to focus on the development and structure of a socially organized way of carrying out the basic scientific strategy.

The distinctive features of science as a social structure are found along 2 dimensions:

  1. the organization of work at a given time – science is able to coordinate the energies of diverse individuals in an effective way (ch 11)

  2. the organization of work across time, the relationships between different times, and with the transmission of ideas between scientific generations – scientific work is cumulative.

Balance in Modern Science

  • Balance between competition and cooperation

    • the message of Merton, Hull, and Kitcher

  • Balance between criticism and trust

    • the message of Kuhn and kind of Shappin

The cumulative structure of science can be gained and lost.

In terms of cooperation and competition within the organization of scientific work at a time, Robert Boyle helped set up a new kind of culture of controlled criticism and a new kind of network of trust.

Alchemy: The precursor to chemistry. A combination of practical work based on detailed recipes and an amazingly strange set of accompanying theories.


15.4 (A Last Challenge)

-> Modern science involves both a general strategy and a complex social structure that carries out the strategy.


15.5 (The Future)

What are the key issues in the near future for philosophy?

  1. What role do frameworks, paradigms, and similar constructs haven our understanding of theory changes science?

  2. What differences are there between different fields and different subcultures science? (e.g. relation between competition and cooperation in science)

  3. We don’t have a theory of representation yet

Progress

  • The idea of looking closely at the relation between the reward structure in science and epistemological issues is a big advance in theories of testing and evidence..

  • The field is less dominated by questions about language, instead focusing on model-building as a crucial part of scientific work
