Philosophy of Science II
University of Oporto, Department of Philosophy
Tommaso Piazza
This 60–hour course on the Philosophy of Science has been taught by me, with slight modifications,
two times, in the second semester of the academic years 2010/11, and 2011/12. The course consists
of thirty 2-hours sessions (28 lectures, and 2 sessions in which students presents their assignments).
It is a mandatory course for second-year undergraduate students of Philosophy (‘Licenciatura em
Filosofia’ in the Portuguese system).
Course Description
The course addresses the question of how science should be interpreted. At the very beginning, I
explain the classical (empiricist) distinction between primary and secondary qualities. Then, by
resting on the first distinction, I introduce the second key distinction between observables (entities
or properties) and unobservable (entities of properties). Then I start to chart the geography. I begin
by presenting Scientific Realism, and factor this position into three distinct components. At the
semantic level, Scientific Realism portrays scientific activity as an attempt to describe (observable
and unobservable) reality, so it portrays scientific claims (about observables and unobservable) as
truth-evaluable assertions. At the metaphysical level, Scientific Realism is the claim that the
(observable and unobservable) entities that science aims to describe exist independently of the
mind. Finally, at the epistemological level, Scientific Realism is the (optimistic and anti-sceptical)
claim that truth about (observable and unobservable) reality is not beyond our epistemic reach. In
opposition to Scientific Realism, various forms of antirealism are then introduced and discussed:
Empiricism and Instrumentalism, which reject the semantic component of Scientific Realism;
scientific constructivism, which rejects the metaphysical component of Scientific Realism; and
constructive empiricism, which rejects the epistemological component of Scientific Realism. I then
expound and critically discuss the major argument for Scientific realism, namely Putnam’s No
Miracle Argument; and the major argument in favour of Scientific anti-realism, namely the socalled Pessimistic meta-induction. The latter argument is critically discussed in the light of the
notion of novel prediction, and of by paying attention to history of science. Finally it is introduce,
and critically discussed, the Underdetermination argument for scientific anti-realism.

Goals of the Course
At the end of this course,
1. Students will have acquired a basic understanding of the Scientific realism/anti-realism
controversy.
2. They will be aware of the standard defense of Scientific Realism as well as of the most
promising attempt to undermine it. Moreover, they will be aware of the most successful
defense of antirealism, and of the realist attempts to undermine it.
3. Students will be able to master the most important notions in philosophy of science, like
primary/secondary qualities, appearance and reality, hipotetico-deductive confirmation,
empirical equivalence, underdetermination. They will be able to apply such concepts to new
examples taken from scientific practice.
4. Students will have become familiar with major authors in philosophy, like Carnap, Mach,
Craig, van Fraassen, Putnam, Smart, Maxwell, Laudan & Leplin.
5. The students will be able to think critically about various topics in the philosophy of
science. The students will be required to write a short paper on a topic of their choice related
to the course’s syllabus, and to present it to the rest of the students in two special sessions at
the end of the course.
Evaluation
25% of total score: paper evaluation (maximum grade: 20 points). 75% of total score:
students will sit a written exam. Students will receive six question; they will have to select
four, and answer them. Each answer will receive a maximum grade of 5 points, so that the
maximum grade of the written exam is 20 points.
