Point of Logic

[Zarathustra]

Is Logic useful for Philosophy in practical way? If yes, in what way logic is practical and useful in real life and for philosophy?
Or is it just for the sake of the interest of the logicians and students who learns the subjects for purely learnings sake?

[Impenitent]

logic is useful when you ignore the fallacy of induction

[nemos]

If you think of logic as the making of logical judgements, it is hard to see how you could do without it. Although even if we exclude reasoning and leave only instincts, the response to environmental incentives should still be logical.
But if you think of logic as a discipline, together with methods and mathematics, then it all depends on what you study and how interested you are in learning it.

In fact, you can try to come out the other way round, to think what things might look like if you ignore logic.

I think this is exactly right, with reservations about the final sentence, because I'm not sure what point Nemos is making there.

But even the Neandertals, 100K years ago, must have understood as a general principle: "if A, then B; if ~A, then (at least probably) ~B".
