Since we cannot be universal and know all that is to be known of everything, we ought to know a little about everything. For it is far better to know something about everything than to know all about one thing. This universality is the best. If we can have both, still better; but if we must choose, we ought to choose the former.

By a peculiar prerogative, not only each individual is making daily advances in the sciences, and may make advances in morality (which is the science, by way of eminence, of living well and being happy), but all mankind together is making a continual progress in proportion as the universe grows older.

If we let ourselves believe that man began with divine grace, that he forfeited this by sin, and that he can be redeemed only by divine grace through the crucified Christ, then we shall find peace of mind never granted to philosophers. He who cannot believe is cursed, for he reveals by his unbelief that God has not chosen to give him grace.
