All great events hang by a single thread. The clever man takes advantage of everything, neglects nothing that may give him some added opportunity; the less clever man, by neglecting one thing, sometimes misses everything.
Arabia was idolatrous when, six centuries after Jesus, Muhammad introduced the worship of the God of Abraham, of Ishmael, of Moses, and Jesus. The Ariyans and some other sects had disturbed the tranquility of the east by agitating the question of the nature of the Father, the son, and the Holy Ghost. Muhammad declared that there was none but one God who had no father, no son and that the trinity imported the idea of idolatry.
Public opinion is a mysterious and invisible power, to which everything must yield. There is nothing more fickle, more vague, or more powerful; yet capricious as it is, it is nevertheless much more often true, reasonable, and just, than we imagine.
Religions are all founded on miracles - on things we cannot understand, such as the Trinity. Jesus calls himself the Son of God, and yet is descended from David. I prefer the religion of Mahomet - it is less ridiculous than ours.
