“Nature has willed that man should, by himself, produce everything that goes beyond the mechanical ordering of his animal existence, and that he should partake of no other happiness or perfection than that which he himself, independently of instinct, has created by his own reason.”

Context: "Behold yon miserable creature. That Point is a Being like ourselves, but confined to the non-dimensional Gulf. He is himself his own World, his own Universe; of any other than himself he can form no conception; he knows not Length, nor Breadth, nor Height, for he has had no experience of them; he has no cognizance even of the number Two; nor has he a thought of Plurality; for he is himself his One and All, being really Nothing. Yet mark his perfect self-contentment, and hence learn this lesson, that to be self-contented is to be vile and ignorant, and that to aspire is better than to be blindly and impotently happy. Now listen."He ceased; and there arose from the little buzzing creature a tiny, low, monotonous, but distinct tinkling, as from one of your Spaceland phonographs, from which I caught these words, "Infinite beatitude of existence! It is; and there is none else beside It."

§ IV
1910s, At the Feet of the Master (1911)
Context: These three great crimes you must avoid, for they are fatal to all progress, because they sin against love. But not only must you thus refrain from evil; you must be active in doing good. You must be so filled with the intense desire of service that you are ever on the watch to render it to all around you — not to man alone, but even to animals and plants. You must render it in small things every day, that the habit may be formed, so that you may not miss the rare opportunity when the great thing offers itself to be done. For if you yearn to be one with God, it is not for your own sake; it is that you may be a channel through which His love may flow to reach your fellow-men.
He who is on the Path exists not for himself, but for others; he has forgotten himself, in order that he may serve them. He is as a pen in the hand of God, through which His thought may flow, and find for itself an expression down here, which without a pen it could not have. Yet at the same time he is also a living plume of fire, raying out upon the world the Divine Love which fills his heart.
The wisdom which enables you to help, the will which directs the wisdom, the love which inspires the will — these are your qualifications. Will, Wisdom and Love are the three aspects of the Logos; and you, who wish to enroll yourselves to serve Him, must show forth these aspects in the world.

The Educational Theory of Immanuel Kant (1904)
Context: Man has his own inclinations and a natural will which, in his actions, by means of his free choice, he follows and directs. There can be nothing more dreadful than that the actions of one man should be subject to the will of another; hence no abhorrence can be more natural than that which a man has for slavery. And it is for this reason that a child cries and becomes embittered when he must do what others wish, when no one has taken the trouble to make it agreeable to him. He wants to be a man soon, so that he can do as he himself likes.

Napoleon : In His Own Words (1916)
Context: Dante has not deigned to take his inspiration from any other. He has wished to be himself, himself alone; in a word, to create. He has occupied a vast space, and has filled it with the superiority of a sublime mind. He is diverse, strong, and gracious. He has imagination, warmth, and enthusiasm. He makes his reader tremble, shed tears, feel the thrill of honor in a way that is the height of art. Severe and menacing, he has terrible imprecations for crime, scourgings for vice, sorrow for misfortune. As a citizen, affected by the laws of the republic, he thunders against its oppressors, but he is always ready to excuse his native city, Florence is ever to him his sweet, beloved country, dear to his heart. I am envious for my dear France, that she has never produced a rival to Dante; that this Colossus has not had his equal among us. No, there is no reputation which can be compared to his.
