…If your mental purview is limited to the present, or if you have imbibed the doctrine that what is called efficiency is the only thing that matters, you will adopt… dubious means. Through them you will be victorious in your immediate purpose, while the more distant consequences may be disastrous. If, on the other hand, you have as part of the habitual furniture of your mind the past ages of man, his slow and partial emergence out of barbarism, and the brevity of his total existence in comparison with astronomical epochs… you will realize that the momentary battle upon which you are engaged cannot be of such importance as to risk a backward step towards the darkness out of which we have been slowly emerging. Nay, more, if you suffer defeat in your immediate objective, you will be sustained by the same sense of its momentariness that made you unwilling to adopt degrading weapons. You will have, beyond your immediate activities, purposes that are distant and slowly unfolding, in which you are not an isolated individual but one of the great army of those who have led mankind towards a civilized existence. If you have attained to this outlook, a certain deep happiness will never leave you, whatever your personal fate may be. Life will become a communion with the great of all ages, and personal death no more than a negligible incident.
…I should seek to make …people vividly aware of the past, vividly realizing that the future of man will in all likelihood be immeasurably longer than his past, profoundly conscious of the minuteness of the planet upon which we live and of the fact that life on this planet is only a temporary incident; and at the same time with these facts which tend to emphasize the insignificance of the individual I should present quite another set of facts designed to impress upon the mind… the greatness of which the individual is capable, and the knowledge that throughout all the depths of stellar space nothing of equal value is known to us. Spinoza long ago wrote of human bondage and human freedom; his form and language make his thought difficult to access to all but students of philosophy, but the essence of what I wish to convey differs little from what he has said.
A man who has once perceived, however temporarily and however briefly, what makes greatness of soul, can no longer be happy if he allows himself to be petty, self-seeking, troubled by trivial misfortuntes, dreading what fate may have in store for him. The man capable of greatness of soul will open wide the windows of his mind, letting the winds blow freely upon it from every portion of the universe. He will see himself and life and the world as truly as our human limitations will permit; realizing the brevity and minuteness of human life, he will realize also that in individual minds is concentrated whatever of value the known universe contains. And he will see that the man whose mind mirrors the world becomes in a sense as great as the world. In emancipation from the fears that beset the slave of circumstance he will experience a profound joy, and through all the vicissitudes of his outward life he will remain in the depths of his being a happy man.
