Spinoza’s philosophy develops in striking ways over the course of his philosophical career. In his first work on metaphysics, the Short Treatise, Spinoza insists that humility is one of the highest virtues and that human beings have no power of their own. But in his final work on metaphysics, the Ethics, Spinoza bluntly declares that humility is not a virtue and argues that our essence simply consists in power. This essay demonstrates the interconnectedness and significance of these apparently distinct shifts. (...) I argue that Spinoza’s re-evaluation of humility is a consequence of his re-thinking of human power and that attention to these shifts puts the debate over acosmism in a new and surprising light.
