Philosophy means love of wisdom.
According to Wikipedia, it combines ethics, metaphysics, epistemology (genuine knowledge) and logic (principles of reasoning).
“There is geometry in the humming of the strings, there is music in the spacing of the spheres.”“As soon as laws are necessary for men, they are no longer fit for freedom.”
“Choose always the way that seems the best, however rough it may be; custom will soon render it easy and agreeable.”
“If there be light, then there is darkness; if cold, heat; if height, depth; if solid, fluid; if hard, soft; if rough, smooth; if calm, tempest; if prosperity, adversity; if life, death.”
“Some are slaves of ambition or money, but others are interested in understanding life itself. These give themselves the name of philosophers (lovers of wisdom), and they value the contemplation and discovery of nature beyond all other pursuits.”
