Epistemologia (LM)

Avviso

Il corso Epistemologia (LM) non verrà erogato nell’anno accademico 2019-2020, e verrà mutuato dal corso Philosophy of computation and Information tenuto dal prof Giuseppe Primiero.

Inductive Logic and Rational Decision

This course aims at developing the basics of probability logic and its application to problems of inductive inference and rational decision. Familiarity with classical propositional logic is a useful pre-requisite for this course.

  1. Logico-mathematical preliminaries (from an elementary algebraic point of view)
  2. Probability logic (a.k.a. inductive logic)
  3. Probability, uncertainty and rationality

Practicalities

Language

The course will be delivered in English if non-Italian speakers are attending. The course-notes however are written in Italian. This guarantees that students who are not proficient in English maximise their understanding of the course material, while giving non-Italian speakers a chance to practice the language.

A tutorial on coherence

Presentation schedule

Please edit this file with your name, id (matricola), presentation topic. I will then schedule all presentations according to their content. Please submit your essay (max 5 pages in standard latex format, or equivalent) by Friday 10th May. Submission means you send the pdf of your essay to all email addresses, including my own. This allows anyone to have a chance to read the essay before your presentation.

Conditional probability 1 (The Sleeping Beauty Problem)

On Sunday, Beauty is put to sleep. He is awakened once on Monday, and put to sleep again after being administered a memory-erasing drug that causes him to forget his awakening. A fair coin is tossed. If and only if the coin falls tails, Beauty is awakened again on Tuesday. He knows all this. When he awakes on Monday, what should his credence be that the coin will fall heads?

Conditional probability 2 (The Monty Hall Problem)

Suppose you’re on a game show, and you’re given the choice of three doors: behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice?

Conditional probability 3 (The Simpson Paradox)

This paradox is the possibility of P(A|B) <P(A|B') even though P(A|B)\ge P(A| B') both under the additional condition C and under the complement C' of that condition.
