In 1676 Leibniz found a pretext to visit Spinoza in The Hague, having learned that Spinoza was at work on a philosophical treatise of great importanc… - Benedictus de Spinoza

Offer with me reverently a tribute to the manes of the holy, rejected Spinoza. The high World-Spirit pervaded him; the Infinite was his beginning and his end; the Universe was his only and his everlasting love. In holy innocence and in deep humility he beheld himself mirrored in the eternal world, and perceived how he also was its most worthy mirror. He was full of religion, full of the Holy Spirit. Wherefore, he stands there alone and unequalled; master in his art, yet without disciples and without citizenship, sublime above the profane tribe.

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.]

He who has a true idea simultaneously knows that he has a true idea, and cannot doubt of the truth of the thing perceived.
