“Marx profoundly affected those who did not accept his system. His influence extended to those who least supposed they were subject to it.”

Quoted as the opening passage of "BOOK ONE: The Functions of Language" in Language in Thought and Action (1949) by S. I. Hayakawa, p. 3
Words and Their Meanings (1940)
Context: A great deal of attention has been paid … to the technical languages in which men of science do their specialized thinking … But the colloquial usages of everyday speech, the literary and philosophical dialects in which men do their thinking about the problems of morals, politics, religion and psychology — these have been strangely neglected. We talk about "mere matters of words" in a tone which implies that we regard words as things beneath the notice of a serious-minded person.
This is a most unfortunate attitude. For the fact is that words play an enormous part in our lives and are therefore deserving of the closest study. The old idea that words possess magical powers is false; but its falsity is the distortion of a very important truth. Words do have a magical effect — but not in the way that magicians supposed, and not on the objects they were trying to influence. Words are magical in the way they affect the minds of those who use them. "A mere matter of words," we say contemptuously, forgetting that words have power to mould men's thinking, to canalize their feeling, to direct their willing and acting. Conduct and character are largely determined by the nature of the words we currently use to discuss ourselves and the world around us.

Context: Neither the wisest constitution nor the wisest laws will secure the liberty and happiness of a people whose manners are universally corrupt. He therefore is the truest friend to the liberty of his country who tries most to promote its virtue, and who, so far as his power and influence extend, will not suffer a man to be chosen into any office of power and trust who is not a wise and virtuous man. We must not conclude merely upon a man's haranguing upon liberty, and using the charming sound, that he is fit to be trusted with the liberties of his country. It is not unfrequent to hear men declaim loudly upon liberty, who, if we may judge by the whole tenor of their actions, mean nothing else by it but their own liberty, — to oppress without control or the restraint of laws all who are poorer or weaker than themselves. It is not, I say, unfrequent to see such instances, though at the same time I esteem it a justice due to my country to say that it is not without shining examples of the contrary kind; — examples of men of a distinguished attachment to this same liberty I have been describing; whom no hopes could draw, no terrors could drive, from steadily pursuing, in their sphere, the true interests of their country; whose fidelity has been tried in the nicest and tenderest manner, and has been ever firm and unshaken.
The sum of all is, if we would most truly enjoy this gift of Heaven, let us become a virtuous people.
