Many of the most influential philosophers of that time, like the Encyclopédistes, Voltaire or Reimarus, were secularists or promoted a deist view: In a nutshell, they proclaimed that nature was the only revelation God has ever made and thus the preoccupation with any other alleged revelation was superfluous.
Johann Albert Heinrich Reimarus (11 November 1729, Hamburg - 6 June 1814, Rantzau, Holstein) was a German physician, natural historian and economist.
