Are humans philosophers, or is philosophy human ?

As it has been said before, most of the great thinkers have ignited their systems by wondering at different sciences. Par example, Aristotel inspired his works from biology, Pythagora or Plato from mathematics, Kant from physics, or Hegel from the indelible flow of history.
I, myself, dare wonder in front of philosophy itself. I question whether philosophy is the expression of the world as percolated through one’s very own sensibility and spirit, or, by shifting the point of view, by philosophising, one opens his mind to notions of intrinsical and subtle essence. In other words, what was first ? Philosophy, or the philosopher ? Man or the idea ?
Are general truths of an irefutable nature, waiting for us to discover, or ponder upon them, or is man creating new concepts and perspectives with every eon that passess ? Are general truths, Ideas or Forms, as you like to call them, real, or possible, which makes all philosophy a fine weavery around them ? Or, on the contrary , it is all a bold affirmation of man’s creativity and whimsical excentricity ?
