“…prejudice and the well-known weaknesses of human nature are to be exploited and thus encouraged.”

Source: What is Property? (1840), Ch. V: "Psychological Explanation of the Idea of Justice and Injustice, and the Determination of the Principle of Government and of Right," Part 2: Characteristics of Communism and of Property
Context: Communism is inequality, but not as property is. Property is the exploitation of the weak by the strong. Communism is the exploitation of the strong by the weak. In property, inequality of conditions is the result of force, under whatever name it be disguised: physical and mental force; force of events, chance, fortune; force of accumulated property, &c. In communism, inequality springs from placing mediocrity on a level with excellence. This damaging equation is repellent to the conscience, and causes merit to complain; for, although it may be the duty of the strong to aid the weak, they prefer to do it out of generosity, — they never will endure a comparison. Give them equal opportunities of labor, and equal wages, but never allow their jealousy to be awakened by mutual suspicion of unfaithfulness in the performance of the common task.
Communism is oppression and slavery. Man is very willing to obey the law of duty, serve his country, and oblige his friends; but he wishes to labor when he pleases, where he pleases, and as much as he pleases. He wishes to dispose of his own time, to be governed only by necessity, to choose his friendships, his recreation, and his discipline; to act from judgment, not by command; to sacrifice himself through selfishness, not through servile obligation. Communism is essentially opposed to the free exercise of our faculties, to our noblest desires, to our deepest feelings. Any plan which could be devised for reconciling it with the demands of the individual reason and will would end only in changing the thing while preserving the name. Now, if we are honest truth-seekers, we shall avoid disputes about words.
Thus, communism violates the sovereignty of the conscience, and equality: the first, by restricting spontaneity of mind and heart, and freedom of thought and action; the second, by placing labor and laziness, skill and stupidity, and even vice and virtue on an equality in point of comfort. For the rest, if property is impossible on account of the desire to accumulate, communism would soon become so through the desire to shirk.

The Never-Ending Wrong (1977)
Context: In 1935 in Paris, living in that thin upper surface of comfort and joy and freedom in a limited way, I met this most touching and interesting person, Emma Goldman, sitting at a table reserved for her at the Select, where she could receive her friends and carry on her conversations and sociabilities over an occasional refreshing drink. She was half blind (although she was only sixty-six years old), wore heavy spectacles, a shawl, and carpet slippers. She lived in her past and her devotions, which seemed to her glorious and unarguably right in every purpose. She accepted the failure of that great dream as a matter of course. She finally came to admit sadly that the human race in its weakness demanded government and all government was evil because human nature was basically weak and weakness is evil. She was a wise, sweet old thing, grandmotherly, or like a great-aunt. I said to her, "It's a pity you had to spend your whole life in such unhappiness when you could have had such a nice life in a good government, with a home and children."
She turned on me and said severely: "What have I just said? There is no such thing as a good government. There never was. There can't be."
I closed my eyes and watched Nietzsche's skull nodding.
