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?
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.
Faith without evidence is, properly, not faith, but prejudice or presumption; faith beyond evidence is superstition, and faith contrary to evidence is either insanity or willful perversity of mind.
Wise men weigh the advantages of any course of action against its drawbacks, and move not an inch until they can see what the result of their action will be; but while they are deep in thought, the men with self-confidence ‘come and see and conquer.’
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.
