Spinoza's teachings were already known outside of Holland during the final years of his life [approximately in his late 30s to early 40s]. So fast di… - Benedictus de Spinoza

[In the 18th century] Whether one reads the underground texts or those of the great Enlightenment authors, one has the impression that Spinozism was everywhere; but at the same time, it can be said, strictly speaking, there were no Spinozists (except as convenient phantoms for apologists); there were only thinkers who make use of Spinoza. Naturally, they could do so with more or less creativity, style, and depth.

In the eyes of his biographers Spinoza was unmistakably an ideal wise man: exclusively concentrated on the precise architecture of his works, perfectly indifferent to material affairs, and liberated from all passions. But an episode in his life is passed over in silence by some biographers, while others consider it only an incomprehensible, youthful whim. Spinoza's father died in 1656. In his family Baruch had the reputation of an eccentric young man who had no practical sense and wasted precious time studying incomprehensible books. Due to clever intrigues (his stepsister Rebecca and her husband Casseres played the main role in this) he was deprived of his inheritance. She hoped the absentminded young man would not even notice. But it happened otherwise.

And if I place so much emphasis on Spinoza, it is indeed not from any subjective preference (I have expressly omitted the objects of such a preference) or to establish him as master of a new autocracy, but because I could demonstrate by this example in a most striking and illuminating way my ideas about the value and dignity of mysticism and its relation to poetry. Because of his objectivity in this respect, I chose him as a representative of all the others. [Original in German: Und wenn ich einen so großen Akzent auf den Spinosa lege, so geschieht es wahrlich nicht aus einer subjektiven Vorliebe (deren Gegenstände ich vielmehr ausdrücklich entfernt gehalten habe) oder um ihn als Meister einer neuen Alleinherrschaft zu erheben; sondern weil ich an diesem Beispiel am auffallendsten und einleuchtendsten meine Gedanken vom Wert und der Würde der Mystik und ihrem Verhältnis zur Poesie zeigen konnte. Ich wählte ihn wegen seiner Objektivität in dieser Rücksicht als Repräsentanten aller übrigen.]
