A good philosopher questions everything.
Acceptance is ignorance.
Without questioning we would not be where we are today. Lets take the world in cave man day’s for example, they had a very 1D view of the world – survival, and that was about it. When people thought, actually thought about the world, it seemed flat, so they accepted it. A 2D view, choosing what appears correct, and assuming that it is.
Now I believe that we live in a 3D world, we question things to more of a degree, and hence have found out that the earth is not flat, but round. In the future who knows, but I don’t think that humanity have reached their full philosophical capacity just yet.
