When you look up the word Philosophy in the Stanford Encyclopedia of PHILOSOPHY, you won’t find a definition. If you look up the word in other prominent sources – e.g., the Internet Encyclopedia of Philosophy and the Catholic (New Advent) Encyclopedia – you will get a long history of what different philosophers thought about the word ‘philosophy’ throughout the ages. All formal articles dealing with the subject end without a crisp definition of this enigmatic term. No one alive today has any idea what Philosophy means or is supposed to be about. You have no choice but to rely on the definition you find in the Wikipedia. However, the Wikipedia is dismissed by many as an informal source. In other words, there is no formal, scientific definition of Philosophy.
The informal definition of Philosophy
The Wikipedia may be regarded as an informal source, but, as a result, it is probably a more important source than the so-called ‘formal’ and ‘respectable’ ones. The Wikipedia provides a version of words as understood by the majority of the population. Therefore, if the ‘formal’ and ‘respectable’ sources which are allegedly peer-reviewed cannot define a term, we have to go with the notion that the great majority of the global population has of that word.
“Philosophy (love of wisdom) is the study of general and fundamental questions about existence, knowledge, values, reason, mind, and language.” (Wikipedia)
The Wikipedia article clarifies that classic philosophical questions include:
Is it possible to know anything and to prove it?
What is most real?
Is there a best way to live?
Is it better to be just or unjust (if one can get away with it)?
Do humans have free will?
