Baruch Spinoza

nineteenth proposition of the seventh book of Euclid,

in order to know, there is no need to know that we know, much less to know that we know that we know.

in order to know that I know, I must first know.

mode in which we perceive an actual reality is certainty

method is nothing else than reflective knowledge

Indeed, for Spinoza, godliness and humanitarianism, love and wisdom, are identical. There is no higher knowledge than the intuitive love for the divine principle and for one’s fellowman; and the greatest happiness comes when man’s love has for its object the knowledge of God.
