John Locke (1632–1704) believed that all knowledge was gained through experience. While Descartes and other Rationalists maintained that ideas can be generated by the mind or inspired by the soul, independent of practical experience, Locke dismissed such notions as unprovable. There was no such thing as innate ideas. He put forth his philosophy in a book called
Locke Versus Hobbes
Locke and his more irascible predecessor, Thomas Hobbes, have much in common. There is no evidence that either was an atheist, but much of their belief system infers that they were. As previously noted, it would have been career (and perhaps literal) suicide to aggressively espouse such a view in those days. Suffice it to say, they minimized, if not outright dismissed, all matters metaphysical. They also had little use for the imperious notion of the Divine Right of Kings.

Whereas Hobbes felt the natural law of man was survival at any cost and the “state of nature” was one of violence and barbarism, Locke believed in a natural law where people had, to paraphrase another famous writer, “certain inalienable rights” such as life, liberty, and the pursuit of happiness. And these rights are to be gained by working for them, not by the
A Social Contract
Locke, like Hobbes, is also famous for his notion of a

Locke believed that the contract is there for the greater good of society and to uphold the inherent rights of the individual.
Two subsequent British empiricists, both Locke supporters, added their unique voices to the Lockean theory.
