1927. The only biography written about Spinoza by someone who knew him well. Spinoza was one of those great men who made himself famous by views that were unusual and unknown to common souls. His father was a Portuguese Jew and because he did not have the means to help his son in business, he allowed Spinoza to study Hebrew literature. Due to the inadequacy of answers to questions voiced to his teacher, Spinoza began to read scripture over and over again, penetrated its obscurity, laid bare its mysteries and brought daylight to the clouds behind which he found truth.
