Is logic essential to philosophy?

Postby A_Seagull on July 17th, 2017, 11:23 pm 

Is logic essential to philosophy? Or does there just need to be a philosophy of logic in the same way that there is a philosophy of mathematics?

Or is logic somehow an integral part of philosophy? And if so how and why?

One cause of confusion is that logic often refers to 'truth'. But what does this 'truth' mean? And how is it related to normative meanings of 'truth'?

First: yes. It is an essential tool in modern analytic philosophy. Perhaps a good person to start with is Russell, who made many contributions to logic and its applications in philosophy:

Another key player, in the logic of epistemology, was Carnap. Also worth a look, in the SEP, or in wiki.

Russell, on truth, and what is needed for a theory of truth. I found this link to have a good intro to the subject.

Logic is integral to thought and communication.
Even to fiction, advertising and lying. Even, oddly enough, to faith: one can't express a spiritual belief or superstition without some internal structure of cause-effect relationships.
The logic of an argument may be convoluted, inauthentic, fallacious, incomplete or fraudulent - but there must be a structure of related ideas that passes as logic before any statement can be recognized as an argument.

Illogic doesn't scan long enough to be followed.

I think you misunderstand my questions. Are you able to provide succinct answers to them?

But what is that logic? What is it that is integral to thought and communication? How can logic be distinguished from illogic?

Didn't I say?
A set of cause-effect relationships that forms a structure of ideas, phenomena, facts or sequence of events.

Not really. Philosophy requires extensive study and reflection. The links will get you started, and help you refine your question. Short answers aren't necessarily going to provide a sense of what thinkers like Godel, Russell, Carnap, et al. spent lifetimes on.

Understanding what might make a statement true is important in logic.

Its OK. I wasn't really expecting sensible answers anyway. :)

I would suggest taking a look at Husserl's "Logical Investigations".
