In a rare lyrical outburst, in the Critique of the Power of Judgement, Kant describes what would befall such a philosopher like Spinoza:

Deceit, violence and envy will always surround him, even though he is himself honest, peaceable and benevolent; and the righteous ones besides himself that he will still encounter will, in spite of all their worthiness to be happy, nevertheless will be subject by nature, which pays no attention to that, to all the evils of poverty, illness, and untimely death, just like all the other animals on the earth, and will always remain thus until one wide grave engulfs them all together (whether honest or dishonest, it makes no difference here), and flings them, who were capable of having believed themselves to be the final end of creation, back into the abyss of the aimless chaos of matter from which they were drawn.
