Spinoza was the supreme rationalist. He saw an endless stream of causality in the world. For him there is no such entity as will or will power. Nothing happens capriciously. Everything is caused by something prior, and the more we devote ourselves to the understanding of this causative network, the more free we become. ... I'm sure he would have said that you are subject to passions that are driven by inadequate ideas rather than by the ideas that flow from a true quest for understanding the nature of reality. ... He states explicitly that a passion ceases to be a passion as soon as we form a more clear and distinct idea of it--that is, the causative nexus underlying the passion. p.269
