Is the self all that can be known to exist?

[Aegon]

Certain fields of philosophy are more practical to study. For example, political philosophy, as I see it, is a way to try and achieve the best possible society under certain sets of circumstances. Aristotle's Politics deals with this. Political philosophy has the ability to be applied in a practical setting. Even lines of thought like Socrates' discussion on what defines justice is still more practical, because if you are searching for ways to create a just society or to act as justly as possible, you will need to decide what justice is. Things can change depending on the conclusion. This isn't the case with stuff like solipsism. Even if it were true, what can I do in response? How could it impact the way I do things or the way a society does something?

Practicality implies goals. What are your goals ? Are you seeking impact? Which sort? Are you seeking societal change ? Of what kind? Why?

I think the goal of philosophy is to reach a truth using logic. But I personally only find philosophy useful if these truths have an impact on the way I do things or the way society does things. Political philosophy can have (and has had) this sort of impact. Solipsism cannot.

Sorry, I usually stay away from this subforum because I'm no fun when it comes to this stuff. If I don't see practicality in something I don't see the point in it at all.
