Schmitt provided a positive reference for Leo Strauss, and approved his work, which was instrumental in winning Strauss the scholarship funding that allowed him to leave Germany. In turn, Strauss's critique and clarifications of "The Concept of the Political" led Schmitt to make significant emendations in its second edition. Writing to Schmitt during 1932, Strauss summarized Schmitt's political theology thus: "ecause man is by nature evil, he therefore needs "dominion". But dominion can be established, that is, men can be unified only in a unity against—against other men. Every association of men is necessarily a separation from other men ... the political thus understood is not the constitutive principle of the state, of order, but a condition of the state." Some of the letters between Schmitt and Strauss have been published.
