“No, there is now no circumstance known in which it can be affirmed that microscopic beings came into the world without germs, without parents similar to themselves. Those who affirm it have been duped by illusions, by ill-conducted experiments, spoilt by errors that they either did not perceive or did not know how to avoid.”

— Louis Pasteur

“Great change can only be effected by unity. But "Union without knowledge is useless; Knowledge without union is powerless." Then what is the right knowledge? Owen said it consisted in knowing that people came into the world without any intention of doing it; and often with limited capacities, and with disadvantages of person, and with instinctive tendencies which impel them against their will, and which disqualifications they did not give themselves…. Dislike dies in the heart of those who understand this, and the spirit of unity arises.”

“Individualism is the self-affirmation of the individual self as individual self without regard to its participation in its world. As such it is the opposite of collectivism, the self affirmation of the self as part of a larger whole without regard to its character as an individual self.”

“While birds can fly, only humans can argue. Argument is the affirmation of our being. It is the principal instrument of human intercourse. Without argument the species would perish.”

Gerry Spence (1929) American lawyer

Context: While birds can fly, only humans can argue. Argument is the affirmation of our being. It is the principal instrument of human intercourse. Without argument the species would perish. As a subtle suggestion, it is the means by which we aid another. As a warning, it steers us from danger. As exposition, it teaches. As an expression of creativity, it is the gift of ourselves. As a protest, it struggles for justice. As a reasoned dialogue, it resolves disputes. As an assertion of self, it engenders respect. As an entreaty of love, it expresses our devotion. As a plea, it generates mercy. As charismatic oration it moves multitudes and changes history. We must argue — to help, to warn, to lead, to love, to create, to learn, to enjoy justice — to be.

“A science only advances with certainty, when the plan of inquiry and the object of our researches have been clearly defined; otherwise a small number of truths are loosely laid hold of, without their connexion being perceived, and numerous errors, without being enabled to detect their fallacy.”

“That the uneducated and the ill-educated should think the hypothesis that all races of beings, man inclusive, may in process of time have been evolved from the simplest monad, a ludicrous one, is not to be wondered at. But for the physiologist, who knows that every individual being is so evolved—who knows, further, that in their earliest condition the germs of all plants and animals whatever are so similar, "that there is no appreciable distinction amongst them, which would enable it to be determined whether a particular molecule is the germ of a Conferva or of an Oak, of a Zoophyte or of a Man";—for him to make a difficulty of the matter is inexcusable.”

“Sane judgment abhors nothing so much as a picture perpetrated with no technical knowledge, although with plenty of care and diligence. Now the sole reason why painters of this sort are not aware of their own error is that they have not learnt Geometry, without which no one can either be or become an absolute artist; but the blame for this should be laid upon their masters, who are themselves ignorant of this art.”
