Selection from – Ethics – Part IV. Of Human Bondage, or the Strength of the Emotions (Page 23)

Spinoza's Words: (an ultimate good is intelligence)

V. Therefore, without intelligence there is not rational life: and things are only good, in so far as they aid man in his enjoyment of the intellectual life, which is defined by intelligence. Contrariwise, whatsoever things hinder man's perfecting of his reason, and capability to enjoy the rational life, are alone called evil.

Comment:

Spinoza again advocates the rational aspect of human life and defines it as intelligence.
