"While I could provide a series of portraits of each thinker, it will be more effective, and more likely to demonstrate their common endeavor, to proceed through a series of propositions that pessimists subscribe to in greater or less degrees. These propositions, which to some extent build on one another, are, in their bluntest form, as follows: that time is a burden; that the course of history is in some sense ironic; that freedom and happiness are incompatible; and that human existence is absurd. Finally, there is a divide between those pessimists, like Schopenhauer, who suggest that the only reasonable response to these propositions is a kind of resignation, and those, like Nietzsche, who reject resignation in favor of a more life-affirming ethic of individualism and spontaneity."
