There is really very little of Machiavelli's one can accept or use in the contemporary world. The one thing I find interesting in Machiavelli is his … - Benedictus de Spinoza

We have thus begun to think of Spinoza's "radicalism" differently than the past century did. Now we see that the bold innovations of Spinoza were only consequences, rather than foundations. The fact that now gains in importance is that — compared to the significance of Descartes, Hobbes, and Leibniz — Spinoza is only of secondary significance in the history of the core sciences, that is, in the history of natural science, on the one hand, and of natural right, on the other. And the fact that Spinoza achieved more general recognition only toward the end of the eighteenth century is now also understandable: he could be accepted only at the moment when the "querelle des anciens et des modemes" within philosophy had been decided on the main point in favor of the moderns, and when what mattered was the restoration, for the purpose of correcting the modern idea, of certain positions of the premodern world that had been knocked over in the first onslaught; for Spinoza — who stood on the foundation of modern philosophy laid by Descartes and Hobbes — had carried along into the modern world, which he already found in existence, the ideal of life of the premodern (ancient-medieval) tradition, the ideal of the (theoretical) knowledge of God.

The perfection of a thing does not annul its existence, but, on the contrary, asserts it. Imperfection, on the other hand, does annul it ; therefore we cannot be more certain of the existence of anything, than of the existence of a being absolutely infinite or perfect—that is, of God. For inasmuch as his essence excludes all imperfection, and involves absolute perfection, all cause for doubt concerning his existence is done away, and the utmost certainty on the question is given. This, I think, will be evident to every moderately attentive reader.

My dear Tyndall—I find that in the midst of my work in Edinburgh I omitted to write to De Vrij, so I have just sent him a letter expressing my pleasure in my being able to co-operate in any plan for doing honour to old Benedict, for whom I have a most special respect.
