what is the relationship of philosophy and logic?

Answer 1

logic is a tool for framing arguments. Philosophy may use logic in its arguments, but often doesn't. Logic may lead to philosophically interesting conclusions but usually doesn't. It may involve purely abstract statements (all A is B) with no reference to the world.

Roughly, logic says if one statement is true, then another statement follows from it, but says nothing about whether the statements are true or useful.

Answer 2

There is no inherent relation.
Philosophy can claim that logic is its property while logic can prove that philosophy is its son. My own view, they may have collaborated in many ways but that does not create any inherent relationship as to its independent existence. Philosophy had created many speculations without the aid of logic while logic had produced many arrangements of thoughts without consulting the standards of some philosophical branches like metaphysics,etc....

Answer 3

Sorry, "somrh," they are Metaphysics, epistemology, ethics, leading directly to political science, and then aesthetics.
None of them make any sense if your automatic epistemology does not follow the rules of logic. We think and speak in propositions. Propositions have specific forms, or they cannot be valid. Syllogicstic logic is when we say "If A, and if B, then C." Each "if must have logic of it's own. And even then the conclusion can be mistakenly illogical.
You may not even know if any of the propositions is illogical. It happens all the time. There are 72 forms of syllogisms, 60 of which lead NECESSARILY to false conclusions. Of the other 12, NONE lead to a necessarily true conclusion.
So you must study, or at least understand, logic if you are to make sense of anything.
For some people, this logic is just natural because it is the way they learned to be, like learning to ride a bicycle on your own. For others, they can't ride a bicycle even with training wheels.

Answer 4

Research stoicism. The Greek word "logos", which is the root of the word logic, literally translates to reason. However, the significance of this word goes far beyond the reaches of what we today consider reasoning.

This is an important topic for any one with an interest in philosophy. It very well may be what separates philosophy from the blind acceptance that goes along with many religions. It would not be advisable to accept the answers on this site as absolute truths.

Answer 5

Philosophy has primarily 5 major branches (although there are a number of other branches and different ways to categorize it):

Metaphysics
Epistemology
Ethics
Aesthetics
Logic

Other branches include things like philosophy of science, social and political philosophy, axiology (which can be thought to be overarching of ethics and aesthetics) and many other divisions.

Logic also can be thought, however, as sort of a branch of mathematics. Most of the developments in logic have occurred in the last two centuries and have primarily been a result of developing logic so that it would be sufficient for dealing with problems in mathematics. Two chief contributors here are Boole and Frege but others are important as well (Hilbert, Russell, De Morgan, Godel, Von Neumann, etc)

In regard to Yaoi Shonen-ai, I'm not entirely clear with what you're disagreeing with but there are some things about logic that you don't seem up to speed on. You seem to be referring to Aristotle's syllogistic logic but quite frankly, Aristotle's logic was insufficient to deal with most issues where analysis comes up, particular mathematics. That's why Frege and others revised much of logic (and formalized it.) In first order predicate logic, there are infinitely many different propositions that follow from the axioms. Most of these are quite trivial. (For example, from P I can infer P or Q, where Q is some proposition. I could do this "addition" indefinitely.)

There are also deviant logics such as intuitionistic logic (which denies excluded middle and restricts, particularly mathematics, to constructive proofs), fuzzy logic (which deals with vague predicates such as "bald" and "pile") and many valued logics (which deal with more than 2 truth values of standard logic), some of which have been suggested as favorable for dealing with results in quantum mechanics.

In addition, there are ways to add to the first order predicate calculus various modalities such as possibility and necessity as well as others (various forms of deontic logic add in "ought" and "permissible").

Answer 6

Perhaps philosophy is your walk through life and logic shows you which way to turn.

Answer 7

Philosophy can be, and often is a personal thing " My dad's philosophy was, blah, blah, blah ", logic is generally accepted by large numbers of people. Who may have different philosophies !

Answer 8

logic is a branch of philosophy
