Science & Fun - Jonathan Graehl

Spinoza:

It is the part of a wise man, I say, to refresh and restore himself in moderation with pleasant food and drink, with scents, with the beauty of green plants, with decoration, music, sports, the theater, and other things of this kind, which anyone can use without injury to another. For the human Body is composed of a great many parts of different natures, which constantly require new and varied nourishment, so that the whole Body may be equally capable of all the things which can follow from its nature, and hence, so that the Mind also may be equally capable of understanding many things.

In other words, please yourself in all ways that you can be pleased. It’s healthy. Spinoza also advises that you not injure others in pursuit of your pleasure - always a popular sentiment.
