“Anytime you have to rely upon your enemy for a job you’re in bad shape.”

Malcolm X (1925–1965) American human rights activist

The Ballot or the Bullet (1964), Speech in Detroit, Michigan (12 April 1964)
Context: So our people not only have to be re-educated to the importance of supporting black business, but the black man himself has to be made aware of the importance of going into business. And once you and I go into business, we own and operate at least the businesses in our community. What we will be doing is developing a situation wherein we will actually be able to create employment for the people in the community. And once you can create some employment in the community where you live it will eliminate the necessity of you and me having to act ignorantly and disgracefully, boycotting and picketing some place else trying to beg him for a job. Anytime you have to rely upon your enemy for a job you’re in bad shape.

“Art is not a mirror to hold up to society, but a hammer with which to shape it.”

Bertolt Brecht (1898–1956) German poet, playwright, theatre director

Mistakenly attributed to Vladimir Mayakovsky in The Political Psyche (1993) by Andrew Samuels, p. 9; mistakenly attributed to Brecht in Paulo Freire: A Critical Encounter (1993) by Peter McLaren and Peter Leonard, p. 80; variant translation: "Art is not a mirror held up to society, but a hammer with which to shape it."
First recorded in Leon Trotsky, Literature and Revolution (1924; edited by William Keach (2005), Ch. 4: Futurism, p. 120): "Art, it is said, is not a mirror, but a hammer: it does not reflect, it shapes."

“These Great Old Ones, Castro continued, were not composed altogether of flesh and blood. They had shape — for did not this star-fashioned image prove it? — but that shape was not made of matter.”

H.P. Lovecraft (1890–1937) American author

Fiction, The Call of Cthulhu (1926)
Context: There had been aeons when other Things ruled on the earth, and They had had great cities. Remains of Them, he said the deathless Chinamen had told him, were still be found as Cyclopean stones on islands in the Pacific. They all died vast epochs of time before men came, but there were arts which could revive Them when the stars had come round again to the right positions in the cycle of eternity. They had, indeed, come themselves from the stars, and brought Their images with Them.
These Great Old Ones, Castro continued, were not composed altogether of flesh and blood. They had shape — for did not this star-fashioned image prove it? — but that shape was not made of matter. When the stars were right, They could plunge from world to world through the sky; but when the stars were wrong, They could not live. But although They no longer lived, They would never really die...

“You can play a role in the shaping of tomorrow’s world by asking yourself questions like, “What kind of world do I want to live in?” and “What does democracy mean to me?””

Jacque Fresco (1916–2017) American futurist and self-described social engineer

There are many other options of organization for the future than those typically discussed today... In order to accomplish this task one must be free of bias and nationalism, and reflect those qualities in the design of policies. How would you approach that? This is a difficult project requiring input from many disciplines.

“The abstraction is often the most definite form for the intangible thing in myself that I can only clarify in paint. …  I found I could say things with color and shapes that I couldn't say any other way — things I had no words for.”

Georgia O'Keeffe (1887–1986) American artist

1970 - 1986, Some Memories of Drawings (1976)
Context: It is surprising to me to see how many people separate the objective from the abstract. Objective painting is not good painting unless it is good in the abstract sense. A hill or tree cannot make a good painting just because it is a hill or a tree. It is lines and colours put together so that they say something. For me that is the very basis of painting. The abstraction is often the most definite form for the intangible thing in myself that I can only clarify in paint. …  I found I could say things with color and shapes that I couldn't say any other way — things I had no words for.<!-- Also quoted in Georgia O’Keeffe: Nature and Abstraction (2007), edited by Richard Marshall, p. 13

“In the long run, we shape our lives and we shape ourselves. The process never ends until we die. And, the choices we make are ultimately our own responsibility.”

Foreword (January 1960)
You Learn by Living (1960)
Context: One's philosophy is not best expressed in words; it is expressed in the choices one makes. In stopping to think through the meaning of what I have learned, there is much that I believe intensely, much I am unsure of. In the long run, we shape our lives and we shape ourselves. The process never ends until we die. And, the choices we make are ultimately our own responsibility.

“We must believe in one God that we may love & fear him. We must believe that he is the father Almighty, or first author of all things by the almighty power of his will, that we may thank & worship him & him alone for our being and for all the blessings of this life < insertion from f 43v > We must believe that this is the God of moses & the Jews who created heaven & earth & the sea & all things therein as is expressed in the ten commandments, that we may not take his name in vain nor worship images or visible resemblances nor have (in our worship) any other God then him. For he is without similitude he is the invisible God whom no eye hath seen nor can see, & therefore is not to be worshipped in any visible shape. He is the only invisible God & the only God whom we are to worship & therefore we are not to worship any visible image picture likeness or form. We are not forbidden to give the name of Gods to Angels & Kings but we are forbidden to worship them as Gods. For tho there be that are called Gods whether in heaven or in earth (as there are Gods many & Lords many) yet to us there is but one God the Father of whom are all things & we in him & our Lord Jesus Christ by whom are all things & we in him, that is, but one God & one Lord in our worship: One God & one mediator between God & man the man Christ Jesus. We are forbidden to worship two Gods but we are not forbidden to worship one God, & one Lord: one God for creating all things & one Lord for redeeming us with his blood. We must not pray to two Gods, but we may pray to one God in the name of one Lord. We must believe therefore in one Lord Jesus Christ that we may behave our selves obediently towards him as subjects & keep his laws, & give him that honour & glory & worship which is due to him as our Lord & King or else we are not his people. We must believe that this Lord Jesus is the Christ, or Messiah the Prince predicted by Daniel, & we must worship him as the Messiah or else we are no Christians. The Jews who were taught to have but one God were also taught to expect a king, & the Christians are taught in their Creed to have the same God & to believe that Jesus is that King.”

“We are joined today by inspiring entrepreneurs from more than 120 countries and many from across Africa. And all of you embody a spirit that we need to take on some of the biggest challenges that we face in the world -- the spirit of entrepreneurship, the idea that there are no limits to the human imagination; that ingenuity can overcome what is and create what needs to be. And everywhere I go, across the United States and around the world, I hear from people, but especially young people, who are ready to start something of their own -- to lift up people’s lives and shape their own destinies. And that’s entrepreneurship. Entrepreneurship creates new jobs and new businesses, new ways to deliver basic services, new ways of seeing the world -- it’s the spark of prosperity. It helps citizens stand up for their rights and push back against corruption. Entrepreneurship offers a positive alternative to the ideologies of violence and division that can all too often fill the void when young people don’t see a future for themselves. Entrepreneurship means ownership and self-determination, as opposed to simply being dependent on somebody else for your livelihood and your future. Entrepreneurship brings down barriers between communities and cultures and builds bridges that help us take on common challenges together. Because one thing that entrepreneurs understand is, is that you don't have to look a certain way, or be of a certain faith, or have a certain last name in order to have a good idea.”

Barack Obama (1961) 44th President of the United States of America

“In between these four whitewashed walls, on this tiled floor, notice the broken corners, how some tiles have been worn smooth, how many feet have passed this way, and look how interesting this trail of ants is, travelling along the joins as if they were valleys, while up above, projected against the white sky of the ceiling and the sun of the lamp, tall towers are moving, they are men, as the ants well know, having, for generations, experienced the weight of their feet and the long, hot spout of water that falls from a kind of pendulous external intestine, ants all over the world have been drowned or crushed by these, but it seems they will escape this fate now, for the men are occupied with other things. […]
Let's take this ant, or, rather, let's not, because that would involve picking it up, let us merely consider it, because it is one of the larger ones and because it raises its head like a dog, it's walking along very close to the wall, together with its fellow ants it will have time to complete its long journey ten times over between the ants' nest and whatever it is that it finds so interesting, curious or perhaps merely nourishing in this secret room […]. One of the men has fallen to the ground, he's on the same level as the ants now, we don't know if he can see them, but they see him, and he will fall so often that, in the end, they will know by heart his face, the color of his hair and eyes, the shape of his ear, the dark arc of his eyebrow, the faint shadow at the corner of his mouth, and later, back in the ants' nest, they will weave long stories for the enlightenment of future generations, because it is useful for the young to know what happens out there in the world. The man fell and the others dragged him to his feet again, shouting at him, asking two different questions at the same time, how could he possibly answer them even if he wanted to, which is not the case, because the man who fell and was dragged to his feet will die without saying a word. Only moans will issue from his mouth, and in the silence of his soul only deep sighs, and even when his teeth are broken and he has to spit them out, which will prompt the other two men to hit him again for soiling state property, even then the sound will be of spitting and nothing more, that unconscious reflex of the lips, and then the dribble of saliva thickened with blood that falls to the floor, thus stimulating the taste buds of the ants, who telegraph from one to the other news of this singularly red manna fallen from such a white heaven.
The man fell again. It's the same one, said the ants, the same ear shape, the same arc of eyebrow, the same shadow at the corner of the mouth, there's no mistaking him, why is it that it is always the same man who falls, why doesn't he defend himself, fight back. […] The ants are surprised, but only fleetingly. After all, they have their own duties, their own timetables to keep, it is quite enough that they raise their heads like dogs and fix their feeble vision on the fallen man to check that he is the same one and not some new variant in the story. The larger ant walked along the remaining stretch of wall, slipped under the door, and some time will pass before it reappears to find everything changed, well, that's just a manner of speaking, there are still three men there, but the two who do not fall never stop moving, it must be some kind of game, there's no other explanation […]. [T]hey grab him by the shoulders and propel him willy-nilly in the direction of the wall, so that sometimes he hits his back, sometimes his head, or else his poor bruised face smashes into the whitewash and leaves on it a trace of blood, not a lot, just whatever spurts forth from his mouth and right eyebrow. And if they leave him there, he, not his blood, slides down the wall and he ends up kneeling on the ground, beside the little trail of ants, who are startled by the sudden fall from on high of that great mass, which doesn't, in the end, even graze them. And when he stays there for some time, one ant attaches itself to his clothing, wanting to take a closer look, the fool, it will be the first ant to die, because the next blow falls on precisely that spot, the ant doesn't feel the second blow, but the man does.”

“One of the things you want to do with a conception like compassion is that you want to start thinking about it like a psychologist, or like a scientist, because compassion is actually definable. The easiest way to approach it is to think about it in Big-5 terms, because it maps onto Agreeableness, which you can break down into Compassion and Politeness. The liberal types, especially the Social Justice types, are way higher in Compassion. It's actually their fundamental characteristic. You might think, 'well, compassion is a virtue.' Yes, it's a virtue, but any uni-dimensional virtue immediately becomes a vice, because real virtue is the intermingling of a number of virtues and their integration into a functional identity that can be expressed socially. Compassion can be great if you happen to be the entity towards which it is directed. But compassion tends to divide the world into crying children and predatory snakes. So if you're a crying child, hey great. But if you happen to be identified as one of the predatory snakes, you better look the hell out. Compassion is what the mother grizzly bear feels for her cubs while she eats you because you got in the way. We don't want to be thinking for a second that compassion isn't a virtue that can lead to violence, because it certainly can. The other problem with compassion - this is why we have conscientiousness - there's five canonical personality dimensions. Agreeableness is good if you are functioning in a kin system. You want to distribute resources equally for example among your children, because you want all of them to have the same chance, and even roughly the same outcome. That is, a good one. But the problem is that you can't extend that moral network to larger groups. As far as I can tell, you need conscientiousness, which is a much colder virtue. It's also a virtue that is much more concerned with larger structures over the longer period of time. And you can think about conscientiousness as a form of compassion too. It's like: 'straighten the hell out, and work hard and your life will go well. I don't care how you feel about that right now.' Someone who's cold, that is, low in agreeableness and high in conscientiousness, will tell you every time. 'Don't come whining to me. I don't care about your hurt feelings. Do your goddamn job or you're going to be out on the street.' One might think, 'Oh that person is being really hard on me.' Not necessarily. They might have your long term best interest in mind. You're fortunate if you come across someone who is disagreeable. Not tyrannically disagreeable, but moderately disagreeable and high in conscientiousness because they will whip you into shape. And that's really helpful. You'll admire people like that. You won't be able to help it. You'll feel like, 'Oh wow, this person has actually given me good information, even though you will feel like a slug after they have taken you apart.' That's the compassion issue. You can't just transform that into a political stance. I think part of what we're seeing is actually the rise of a form of female totalitarianism, because we have no idea what totalitarianism would be like if women ran it, because that's never happened before in the history of the planet. And so, we've introduced women into the political sphere radically over the past fifty years. We have no idea what the consequence of that is going to be. But we do know from our research, which is preliminary, that agreeableness really predicts political correctness, but female gender predicts over and above the personality trait, and that's something we found very rarely in our research. Usually the sex differences are wiped out by the personality differences, but not in this particular case. On top of that, women are getting married later, and they're having children much later, and they're having fewer of them, and so you also have to wonder what their feminine orientation is doing with itself in the interim, roughly speaking. A lot of it is being expressed as political opinion. Fair enough. That's fine. But it's not fine when it starts to shut down discussion.”

“You put the government on the spot when you even mention Vietnam. They feel embarrassed — you notice that?… It's just a trap that they let themselves get into. … But they're trapped, they can't get out. You notice I said 'they.' They are trapped, They can't get out. If they pour more men in, they'll get deeper. If they pull the men out, it's a defeat. And they should have known that in the first place. France had about 200,000 Frenchmen over there, and the most highly mechanized modern army sitting on this earth. And those little rice farmers ate them up, and their tanks, and everything else. Yes, they did, and France was deeply entrenched, had been there a hundred or more years. Now, if she couldn't stay there and was entrenched, why, you are out of your mind if you think Sam can get in over there. But we're not supposed to say that. If we say that, we're anti-American, or we're seditious, or we're subversive…. They put Diem over there. Diem took all their money, all their war equipment and everything else, and got them trapped. Then they killed him. Yes, they killed him, murdered him in cold blood, him and his brother, Madame Nhu's husband, because they were embarrassed. They found out that they had made him strong and he was turning against them…. You know, when the puppet starts talking back to the puppeteer, the puppeteer is in bad shape….”

“If thou make any law or establish any custom for the general good, be the first to submit thyself thereto; then does a people show more regard for justice nor refuse submission when it has seen their author obedient to his own laws. The world shapes itself after its ruler's pattern, nor can edicts sway men's minds so much as their monarch's life; the unstable crowd ever changes along with the prince.”

“More than 20 years earlier a small band of Hindu students and thoughtful gentlemen used to meet secretly to discuss the effects of British rule in India. The home charges and the transfer of capital from India to England in various shapes, and the exclusion of the children of the country from any share or voice in the administration of their own country, formed the chief burden of their complaint.”
