Some folks do seem to fear what they might find out, but they are not philosophers. Philosophy cannot be concerned with what we like and don't like.

Hi TVCL.I see you've tried to get to the bottom of this issue but I;m not sure it needs so many words. Logic cannot prove a truth about Reality, (as Aristotle points out) but it can find truths for us. I cannot see where 'usefulness' enters the picture. A thing is useful only if we use it, such that usefulness is not a property of information or things. A hammer is not useful if we only have a screw.

. . 25. Therefore, it is the goal of possessing an understanding of the truth that makes sense that justifies adherence to logic; it is the usefulness of logic for the end of achieving this goal that justifies adherence to it and makes it necessary in our search for truth.

I'd agree with this. For this reason metaphysics is a science of logic.

You make a good argument against paraconsistent logic, since we cannot understand the results it produces.

Jack Cummins ; " I simply wish to ask the question of what is the purpose of philosophy?"

To learn the truth.

Unless you're asking about university philosophy, which appears to have no purpose. .
