logic

Unread postby Massimo » 30 Apr 2013 16:18

ancient greek defined the universe as kosmos (κόσμος)
the word kosmos expresses the idea of an harmonious sistem driven by logic
logic tells us how we ought to reason if we want to reason correctly
the correct principles of reasoning is not the same as studying the psychology of reasoning
the psychology of reasoning tells us about the actual reasoning habits of people, including their mistakes
a psychologist studying reasoning might be interested in how people's ability to reason varies with age
but such empirical facts are of no concern to the logician

To discover truths is the task of all sciences;
it falls to logic to discern the laws of truth.
... I assign to logic the task of discovering the laws of truth, not of assertion or thought.

Gottlob Frege (1848-1925)
