For the elitist - Variations on the correct and ideal ultimate knowledge, and means of living life and one's outlook.
For the intelligent - It's a means to study the borders of one's own knowledge, and to push one's own cognitive boundaries. It's a way of understanding what one thinks one understands, questioning how one understands what they do, justifying one's knowledge base, and growing as an individual entity capable of acknowledging, perceiving, conceptualising, formulating, predicting, evaluating, and studying the reality one is a part of.
For the open-minded - A wide field of study bursting at the seems with knowledge applicable to almost each and every situation imaginable. A subject wherein there is no correct answer, nor could ever be one, but that does not cease the mind's curiosity. "I know one thing: that I know nothing at all."
For the unwilling - It's a word that means and encompasses one's own life and ideal. "My Philosophy is simple...", "Well, my Philosophy is..." ect.
For the insular - It's a word that symbolises a weakness, the weakness of searching for things that don't matter. "Why bother with metaphysics? What beyond reality is going to get you food, a car, a tv, a house? It's stupid."
For the shallow - It's a means to prove your knowledge is better than others'.

"If an artist of any of the arts does not experiment, play, nor venture beyond their own capacities, then they may as well put down their instrument of creation, for if one does not search for new frontiers of expansion, they run the risk of mindlessly creating works of generic monotonousness. One must satire their own works to stay unique, and to create pieces that inspire the next generation to push their own creativity even further, and within creativity lies an undiscovered genius."
