So, are you saying that you consider the observations part of the philosophy, or did you have something else in mind?
Observations can be used to support a position, but ISTM they hardly provide a reason for believing something else. It is the logic (or whatever alternative you propose) that links the ideas to observations. The observations simply anchor the argument to our reality, rather than say the starwars "universe" or the matrix "universe".

The logic or alternative would be the gist of the philosophizing that philosophers do, as far as I see.
