"Logic, on which your school lays such stress, he held to be of no effect either as a guide to conduct or as an aid to thought. Natural Philosophy he deemed all‑important."
I am wondering what exactly do we mean by logic, does the above text from Cicero refer to things such as syllogisms e.g.
1. Socrates is a man
2. All men die
3. Socrates will die therefore
One criticism I have is that it solves nothing, there are famous arguments for Gods existence in catholic tradition but they really have no power of demonstration or convincing.
