Sentimus experimurque, nos aeternos esse. - Benedictus de Spinoza

Spinoza's ethical views are inextricably intertwined with his metaphysics, and it may be doubted whether his metaphysics is as good as is supposed by followers of Hegel. But the general attitude towards life and the world which he inculcates does not depend for its validity upon a system of metaphysics. He believes that all human ills are to be cured by knowledge and understanding; that only ignorance of what is best makes men think their interests conflicting, since the highest good is knowledge, which can be shared by all. But knowledge, as he conceives it, is not mere knowledge as it comes to most people; it is “intellectual love,” something coloured by emotion through and through. This conception is the key to all his valuations.

Las traslúcidas manos del judío Labran en la penumbra los cristales Y la tarde que muere es miedo y frío. (Las tardes a las tardes son iguales.) Las manos y el espacio de jacinto Que palidece en el confín del Ghetto Casi no existen para el hombre quieto Que está soñando un claro laberinto. No lo turba la fama, ese reflejo De sueños en el sueño de otro espejo, Ni el temeroso amor de las doncellas. Libre de la metáfora y del mito abra un arduo cristal: el infinito Mapa de Aquél que es todas Sus estrellas. (Here in the twilight the translucent hands Of the Jew polishing the crystal glass. The dying afternoon is cold with bands Of fear. Each day the afternoons all pass The same. The hands and space of hyacinth Paling in the confines of the ghetto walls Barely exists for the quiet man who stalls There, dreaming up a brilliant labyrinth. Fame doesn't trouble him (that reflection of Dreams in the dream of another mirror), nor love, The timid love women. Gone the bars, He's free, from metaphor and myth, to sit Polishing a stubborn lens: the infinite Map of the One who now is all His stars.) [Translated from the Spanish by Willis Barnstone]

I will not attempt to describe here the many lessons that I learned in the study of Spinoza, lessons that in several respects laid the foundation of my philosophy.
