The word philosophy, when broken down, comes from the Greek roots philo- meaning "love" and -sophos, meaning "wisdom". So simply put, philosophy is the love of knowledge and the passion to seek all that is true in the natural world. Unbeknownst to many, philosophy is the mother of all disciplines ranging from society and politics to technology and quantum. Philosophy is not something of the past. It surrounds us today and we have current day philosophers amongst us. You just may not see them. They work above the discipline level and reside in the philosopher's realm.
A philosopher is a person that questions everything and admits when they are wrong. A sort of Jack of all trades. As the saying goes, "Jack of all trades but master of none. Yet more often better, than the master of one." This is very accurate for the philosopher. The only ones that seek degrees in philosophy are those that wish to profess at a university. A philosopher does not seek a degree but sometimes they stumble upon a Phd for one reason or another. They are capable of hopping between multiple disciplines, at one time, and gaining a firm understanding for those disciplines which allows them the ability to see things that the individual master could not have fathomed. This is how new disciplines come to light and are added to the lists of academia. Through their quest for more and more knowledge, the philosopher begins to shed the simple desires that Plato's pitiful prisoners remain focused on, leaving them in the state of Eudaimonia.
