I saw there was no boundary lines between vegetable and animal life, and hence no beginning nor end to either... All physical phenomena, at their best, are dull and murky till they come up into spiritual life. As an illustration that every law has its universality take the familiar law or principle that action and reaction are equal. What is this but reaping the whirlwind after one has sown the wind, or how does natural law differ from this teaching: ‘Whatsoever a man soweth that shall he also reap?’ Are they aught but different strains in the great cosmic melody?
Whoever sets out to persuade men to accept a new idea, or one which seems to be new, not just as an idea, but as a truth that is felt, should know beforehand that the human mind is not a blank sheet, on which one an write with ease, and should not therefore grieve or despair when he finds that people do not pay attention to him.
The first real mental illumination I remember to have experienced was when I saw that the universe exists in each of its individual atoms - that is, the universe is the result of a few simple processes infinitely repeated. When a drop of water has been mathematically measured, every principle will have been used which would be called form in the measurement of the heavens. All life on the globe is sustained by digestion and assimilation; when by voluntary and traumatic action these stop death follows. The history of an individual mind is the history of the race. Know one thing in its properties and relations and you will know all things.
Just as a tested and rugged virtue of the moral hero is worth more than the lovely, tender, untried innocence of the child, so is the massive strength of a soul that has conquered truth for itself worth more than the soft peach-bloom faith of a soul that takes truth on trust.
For truth there is no deadline.
Sentiment and principle are often mistaken for each other, though, in fact, they widely differ. Sentiment is the virtue of ideas; principle the virtue of action. Sentiment has its seat in the had; principle, in the heart. Sentiment suggest fine harangues and subtle distinctions; principle conceives just notions, and performs good actions in consequence of them. Sentiment refines away the simplicity of truth, and the plainness of piety; and "gives us virtue in words, and vice in deeds."
It is a fundamental principle that no person can entirely free himself from taking the people in his environment into consideration. When doing something in the presence of others, it is impossible not to think about how other people will view what you are doing... Any good act you do will be much purer if others are not aware of you.
The simple truth is, that there has lived on the earth, “appearing at intervals,” for thousands of years among ordinary men, the first faint beginnings of another race; walking the earth and breathing the air with us, but at the same time walking another earth and breathing another air of which we know little or nothing, but which is, all the same, our spiritual life, as its absence would be our spiritual death. This new race is in act of being born from us, and in the near future it will occupy and possess the earth.
The life which is in man is eternal, as all life is eternal; that the soul of man is as immortal as God is; that the universe is so built and ordered that without any peradventure all things work together for the good of each and all; that the foundation principle of the world is what we call love, and that the happiness of every individual is in the long run absolutely certain.
