less: "For their paths are perverted, and they know not peace," saith the prophet.[1] "But foolish and unlearned questions" the divine Paul exhorted to "avoid, because they gender strifes."[2] And Æschylus exclaims:
"In what profits not, labour not in vain."
For that investigation, which accords with faith, which builds, on the foundation of faith, the august knowledge of the truth, we know to be the best. Now we know that neither things which are clear are made subjects of investigation, such as if it is day, while it is day; nor things unknown, and never destined to become clear, as whether the stars are even or odd in number; nor things convertible; and those are so which can be said equally by those who take the opposite side, as if what is in the womb is a living creature or not.
