If this is so, then the placement of the Mishkan at the heart of the camp suggests that societies need, in the public domain, a constant reminder of the presence of God. That, after all, is why the Mishkan appears in Exodus, not Genesis. Genesis is about individuals, Exodus about societies. Significant thinkers believed likewise. John Locke, the pioneer of toleration, thought so. He considered that atheists were ineligible for English citizenship since membership was gained by swearing an oath of allegiance, and an oath, being a vow to God, could not be sworn by an atheist.[10] In his farewell address, George Washington said: Of all the dispositions and habits which lead to political prosperity, religion and morality are indispensable supports...let us with caution indulge the supposition that morality can be maintained without religion. Whatever may be conceded to the influence of refined education on minds of peculiar structure, reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle.[11
