human understanding owes much to the passions, which, by common consensus, also owe a great deal to it. It is by their activity that our reason is perfected. We seek to know only because we desire to find enjoyment; and it is impossible to conceive why someone who had neither desires nor fears would go to the bother of reasoning. The passions in turn take their origin from our needs, and their progress from our knowledge.
