"Spinoza, the most logical and consistent of atheists—I mean of those who deny the persistence of individual consciousness through indefinite future time—and at the same time the most pious, Spinoza devoted the fifth and last part of his Ethics to elucidating the path that leads to liberty and to determining the concept of happiness. [...] For Spinoza, who was a terrible intellectualist, happiness (beatitudo) is a concept, and the love of God an intellectual love."
