The world of to-day attaches a large importance to mental independence, or thinking for oneself; yet the manner in which these things are cultivated is very partial. In some matters we are, perhaps too independent (for we need to think socially as well as to act socially); but in other matters we are not independent enough; we are hardly independent at all. For we always interpret mental independence as being independence of old things. But if the mind is to stand in a real loneliness and liberty, and judge mere time and mere circumstances, and all the wasting things of this world, if the mind is really a strong and emancipated judge of things unbribed and unbrowbeaten, it must assert its superiority, not merely to old things, but to new things.

It must forsee the old age of things still in a strenuous infancy. It must stand by the tombstone of the babe unborn. It must treat the twentieth century as it treats the twelfth, as something which by its own nature has already had an end. A free man must not only be free from the past; a free man must be free from the future. He must be ready to face the rising and increasing thing, and to judge it by immortal tests. It is a very poor mark of courage, in comparison, that we are ready to strike at ancient wrongs. Our courage shall be tested by whether we are ready to strike at youthful and full-blooded wrongs; wrongs that have all their life before them, wrongs that are as sanguine as the sunrise, and as fresh as the flowers.
