Is it not true that for every person the course of life is along the line of least resistance, and that in this the movement of humanity is like the movement of material bodies?

So great was the preference given to sacred over profane learning that Christianity had been in existence fifteen hundred years, and had not produced a single astronomer.

I have to deplore the systematic manner in which the literature of Europe has continued to put out of sight our obligations to the Muhammadans. Surely they cannot be much longer hidden.

He has indelibly written it on the heavens as any one may see who reads the names of the stars on a common celestial globe.

Antiquity was often delighted to cast a halo of mythical glory around its illustrious names. The immortal works of this great philosopher seemed to entitle him to more than mortal honors. A legend into the authenticity of which we will abstain from inquiring, asserted that his mother, Perictione, a pure virgin, suffered an immaculate conception through the influence of Apollo. The god declared to Ariston, to whom she was about to be married, the parentage of the child.
