Some philosophers merely argue their philosophies. When they finish their disputation, they hang up the tools of their trade, go home, and indulge in the well-earned pleasure of private life. Other philosophers live their philosophies. They treat as useless any philosophy that does not determine the manner in which they spend their days, and they consider pointless any part of life that has no philosophy in it. They never go home.
Spinoza belonged unambiguously to the latter group.
