...Humiliated beyond sufferance, Uriel went home, wrote a fierce denunciation of his persecutors, and shot himself. This was 1640. At that time Baruc… - Benedictus de Spinoza

And what this Lange has to say about the Hegelian method and my application of the same is simply childish. First, he understands rien [nothing] about Hegel's method and, therefore, second, still less about my critical manner of applying it. In one respect he reminds me of Moses Mendelssohn. That prototype of a windbag once wrote to Lessing asking how he could possibly take ‘that dead dog Spinoza’ au sérieux ! In the same way, Mr Lange expresses surprise that Engels, I, etc., take au sérieux the dead dog Hegel, after Büchner, Lange, Dr Dühring, Fechner, etc., had long agreed that they—poor dear—had long since buried him.

Spinoza was a republican democrat and a supporter of the politician Johan De Witt (1625–72), an opponent of the House of Orange. After De Witt's death, the aristocratic Orange faction took power and restored a more conventional social order (which was subsequently imposed on Britain when one of them acquired the English throne in 1689). By that time ‘Spinozism’ was already a thriving underground cult with ardent supporters in many countries: ‘The battle was on to fix the image of the dying Spinoza in the perceptions and imagination of posterity,’ Israel writes, since ‘the final hours of a thinker who seeks to transform the spiritual foundations of the society around him become heavily charged with symbolic significance in the eyes of both disciples and adversaries.’ Plainly, this battle still continues. It is not to disregard or minimise such a striking lineage to observe that Spinozism had limitations associated with the society it came from, in which countries were struggling to emerge from absolutism and theocratic tyranny. Today, Spinoza's greatness has to be defended against the delusions of a belated progeny, rather as Marx had to be in the later 19th and 20th centuries.

It was not until the middle of the seventeenth century that pantheism was exhibited in its purest form by the great Baruch Spinoza; he gave for the totality of things a definition of substance in which God and the world are inseparably united. The clearness, confidence, and consistency of Spinoza's monistic system are the more remarkable when we remember that this gifted thinker of two hundred and fifty years ago was without the support of all those sound empirical bases which have been obtained in the second half of the nineteenth century. We have already spoken, in the first chapter, of Spinoza's relation to the materialism of the eighteenth and the monism of the nineteenth century. The propagation of his views, especially in Germany, is due, above all, to the immortal works of our greatest poet and thinker, Wolfgang Goethe. [Original in German: Erst in der zweiten Hälfte des 17. Jahrhunderts wurde durch den großen Baruch Spinoza das System des Pantheismus in reinster Form ausgebildet; er stellte für die Gesamtheit der Dinge den reinen Substanzbegriff auf, in welchem »Gott und Welt« untrennbar vereinigt sind. Wir müssen die Klarheit, Sicherheit und Folgerichtigkeit des monistischen Systems von Spinoza heute um so mehr bewundern, als diesem gewaltigen Denker vor 250 Jahren noch alle die sicheren empirischen Fundamente fehlten, die wir erst in der zweiten Hälfte des 19. Jahrhunderts gewonnen haben. Das Verhältnis von Spinoza zum späteren Materialismus im 18. und zu unserem heutigen Monismus im 19. Jahrhundert haben wir bereits im ersten Kapitel besprochen. Zur weiteren Verbreitung desselben, besonders im deutschen Geistesleben, haben vor allem die unsterblichen Werke unseres größten Dichters und Denkers beigetragen, Wolfgang Goethe.]
