"There are times when the assertion of great principles is the best service a man can render society. The present is a moment of bewildering excitement, when men's minds are stormed and darkened by strong passions and fierce conflicts; and also a moment of absorbing worldliness, when the moral law is made to bow to expediency, and its high and strict requirements are denied, or dismissed as metaphysical abstractions or impracticable theories. At such a season, to utter great principles without passion, and in the spirit of unfeigned and universal good-will, and to engrave them deeply and durably on men's minds, is to do more for the world, than to open mines of wealth, or to frame the most successful schemes of policy."

“God deliver us all from prejudice and unkindness, and fill us with the love of truth and virtue.”

“A clear thought, a pure affection, a resolute act of a virtuous will, have a dignity of quite another kind, and far higher than accumulations of brick and granite and plaster and stucco, however cunningly put together.”

“War is to be ranked among the most dreadful calamities which fall on a guilty world; and, what deserves consideration, it tends to multiply and perpetuate itself without end. It feeds and grows on the blood which it sheds. The passions, from which it springs, gain strength and fury from indulgence.”

“We are able to discern not only what we already are, but what we may become, to see in ourselves germs and promises of a growth to which no bounds can be set, to dart beyond what we have actually gained to the idea of perfection as the end of our being. It is by this self-comprehending power that we are distinguished from the brutes, which give no signs of looking into themselves. Without this there would be no self-culture, for we should not know the work to be done; and one reason why self-culture is so little proposed is, that so few penetrate into their own nature. To most men, their own spirits are shadowy, unreal, compared with what is outward. When they happen to cast a glance inward, they see there only a dark, vague chaos. They distinguish, perhaps, some violent passion, which has driven them to injurious excess; but their highest powers hardly attract a thought; and thus multitudes live and die as truly strangers to themselves as to countries of which they have heard the name, but which human foot has never trodden.”

“I affirm, and would maintain, that true religion consists in proposing, as our great end, a growing likeness to the Supreme Being. Its noblest influence consists in making us more and more partakers of the Divinity. For this it is to be preached. Religious instruction should aim chiefly to turn men's aspirations and efforts to that perfection of the soul, which constitutes it a bright image of God. Such is the topic now to be discussed; and I implore Him, whose glory I seek, to aid me in unfolding and enforcing it with simplicity and clearness, with a calm and pure zeal, and with unfeigned charity.”

“All noble enthusiasms pass through a feverish stage, and grow wiser and more serene.”
