Literally, the love of wisdom. But in modern acceptation, philosophy is a general term denoting an explanation of the reasons of things; or an investigation of the causes of all phenomena both of mind and of matter.

'No one believes justice to be a good when it is kept private, since, wherever either person thinks he can do injustice with impunity, he does it. Indeed, every man believes that injustice is far more profitable to himself than justice.
The King James bible:
'As it is written, There is none righteous, no, not one: There is none that understandeth, there is none that seeketh after God. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.'
'And whosoever was not found written in the book of life was cast into the lake of fire.' (KJB, Revelation 20:15)
