An active scepticism is one which constantly aims at overcoming itself, and arriving by means of regulated experience at a kind of conditioned certainty.
The general nature of the sceptical mind is its tendency to inquire whether any particular predicate really attaches to any particular object; and the purpose of the inquiry is safely to apply in practice what has thus been discovered and proved.
The mind endowed with active powers and keeping with a practical object to the task that lies nearest, is the worthiest there is on earth.
Perfection is the measure of heaven, and the wish to be perfect the measure of man.
Not only what is born with him, but also what he acquires, makes the man.
