Why it’s false that Muhammad lived ‘in the full light of history’

“In place of the mystery under which the other religions have covered their origins, [Islam] was born in the full light of history; its roots are on the surface. The life of its founder is as well known to us as that of any sixteenth-century reformer. We can follow year by year the fluctuations of his thought, his contradictions, his weaknesses.” — Ernest Renan, “Muhammad and the Origins of Islam” (1851)
