Did philosophers actually see the world as they described it?

When I read Heidegger, or Descartes, Bergson or Merleau-Ponty it always appears to me:

1. Well first, what kind of ~~drugs~~...mental state did they achieve that they write these kind of stuff? It would be a complete shift in perspective! Maybe like some of the spiritual leaders'.
2. Is this just an intellectual "game"? Is it just theorising, but experience more or less the ame way as usual mortals? Or actually lived in "another world" as many of them write it.

Unlike straightworward intellectualisation like theoretical physics, this is a radically different way to see/live the world.

Philosophers typically lay out their methodologies and motivations, so it's not impossible to see where they're coming from and to what ends. In fact, I'd say it's crucial to understanding their philosophy.

It's theorizing and experiencing the way as everyone else. The world they theorize about is our world, and not a game but a serious inquiry into what is.

I'd say that the field which gives us things like time dilation, wave–particle duality, quantum non-locality, dark matter, etc. isn't all that more straightfoward or any less radical in theorizing about the world.
