“As shorthand, when the phenomena are suitably simple, words such as equilibrium and stability are of great value and convenience. Nevertheless, it should be always borne in mind that they are mere shorthand, and that the phenomena will not always have the simplicity that these words presuppose.”

“Phenomena appear, in a word, to be explicable on the ground of development.”
We have already seen that various leading animal forms represent stages in the embryotic progress of the highest—the human being. Our brain goes through the various stages of a fish's, a reptile's, and a mammifer's brain, and finally becomes human.

Context: What does cause depression of spirits? Heavy head and heavy heart, and no sufficient reason for either, that I know of. I am out of doors every day, and have nothing unusual to trouble me; yet every interval of thought is clouded; there is no rebound, no rejoicing as it is my nature to rejoice, and as all things teach me to do. We are strange phenomena to ourselves, when we will stop to gaze at ourselves; but that I do not believe in; there are pleasanter subjects, and self is a mere speck on the great horizon of life.
