philosophy schools

"Philosophy" exists 'in' you(it is you) - you just need to let your 'self' hear it!

Supersticion.

There is no such thing as 'Philosophy'.

'Philosophy' is a conceptualization of the end result of 'philosophizing'. 'Philosophy' represents a 'conclusion', the end of thinking/Be-ing.

'Philosophizing' is an 'opening' and an 'un-covering' of who you are.

'Philosophy' is the covering up of who you are by reducing who you are to a 'philosophical concept' and the subsequent argument about who's right about the concept.

'Philosophizing doesn't happen at the level of opinions, speculation, or extrapolation of what you are presented with by the world.

'Philosophizing' is the uncovering of who you are and the subsequent 'showing up' of who you are in the 'world'. 'You', Be-ing, are the source of the 'world'. You are not the effect of the reflection of the 'world' you see.

Wake up.

OBTW - you have an internal speaker. You aren't your internal speaker.

What about if you have more than one speaker?

The original question is unclear. Different philosophical schools, just as different philosophers, may present unique perspectives or use different methods, but the philosophical project itself seems to have been consistent throughout history.

what project?

Mostly it's language. Different ways to describe the same things lead to different ways of relating to them.

You speak as if your words are absolute and undeniable truths.

Elsewhere you wrote that we are not the inner voice (or some such), but we have an inner voice.
That's a good example of how choosing different words can result in us relating to issues very differently, even disagreeing on issues of semantics to the point where we become bitter enemies.

Are you your left hand (along with every other component that makes up 'you')? Or do you have a left hand?
Do you see that whichever way we decide to describe it depends on the context?
If the context is your emotional state vs your physical appendages, you might say that you have a left hand, and it is perfectly meaningful. For the purposes of that moment, the hand is not part of what constitutes 'you' at that moment.
If the context is playing basketball, where your left hand is a key component of what makes up your identity at that moment, it is more meaningful to say that your left hand is you. It's not something you have, but something you are.

But the key point I am trying to make is that these two different ways of perceiving and thinking about something can lead us to extract different philosophies from it. In some cases even conflicting philosophies.
