Fear breeds superstition. - Benedictus de Spinoza

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]

He [Nicolas Malebranche] cannot give up the principles which the Catholic Church imposes on him. He carries forward that process of rationalisation in Christian ethics which Descartes began, and which, like the attempt to restore an older theology, finds its fulfilment in Spinoza. It is Spinoza who is the first to create a wholly metaphysical ethics, free from all trace of its theological origin. Spinoza thus completes for continental ethics the separation between morality and religion which English empiricism, in spite of many relapses, had effected under the leadership of Bacon.

Of all heroes, Spinoza was Einstein's greatest. No one expressed more strongly than he a belief in the harmony, the beauty, and, most of all, the ultimate comprehensibility of nature.
