Spinoza, with his determinism , believes that man and nature must be unified under a consistent set of laws; God and nature are one, and there is no free will . Contrary to most philosophers of his time and in accordance with most of those of the present, Spinoza rejects the dualistic assumption that mind, intentionality , ethics, and freedom are to be treated as things separate from the natural world of physical objects and events.  His goal is to provide a unified explanation of all these things within a naturalistic framework, and his notion of conatus is central to this project. For example, an action is "free", for Spinoza, only if it arises from the essence and conatus of an entity. There can be no absolute, unconditioned freedom of the will, since all events in the natural world, including human actions and choices, are determined in accord with the natural laws of the universe, which are inescapable. However, an action can still be free in the sense that it is not constrained or otherwise subject to external forces. 
The “Two Treatises of Government” (1690) offered political theories developed and refined by Locke during his years at Shaftesbury’s side. Rejecting the divine right of kings, Locke said that societies form governments by mutual (and, in later generations, tacit) agreement. Thus, when a king loses the consent of the governed, a society may remove him—an approach quoted almost verbatim in Thomas Jefferson’s 1776 Declaration of Independence . Locke also developed a definition of property as the product of a person’s labor that would be foundational for both Adam Smith’s capitalism and Karl Marx’s socialism.
Calvin: The hard part for us avant-garde post-modern artists is deciding whether or not to embrace commercialism. Do we allow our work to be hyped and exploited by a market that's simply hungry for the next new thing? Do we participate in a system that turns high art into low art so it's better suited for mass consumption?
Of course, when an artist goes commercial, he makes a mockery of his status as an outsider and free thinker. He buys into the crass and shallow values art should transcend. He trades the integrity of his art for riches and fame.
Oh, what the heck. I'll do it.
Hobbes (rolling his eyes): That wasn't so hard.
