Context: Bus stops are far more interesting and useful places to have art than in museums. Graffiti has more chance of meaning something or changing stuff than anything indoors. Graffiti has been used to start revolutions, stop wars, and generally is the voice of people who aren't listened to. Graffiti is one of those few tools you have if you have almost nothing. And even if you don't come up with a picture to cure world poverty you can make somebody smile while they're having a piss.

version in original Dutch / citaat van Jopie Huisman, in het Nederlands: Door de jaren heen heb ik van alles en nog wat bewaard aan dingen en voorwerpen die ik in mijn leven in de handel tegenkwam, als ze gevoelswaarde voor me hadden. Altijd eenvoudig gebruiksgoed en gereedschap van de boer, de smid, de timmerman, de bakker enzovoorts. Dingen waarin ik de strijd om het bestaan het duidelijkst weerspiegeld zag vond ik het mooist.. ..afgetrapte oude schoenen, broeken, jassen, hoeden en kindervestjes, die ik in de vodden vond, vaak tot in den treure versteld en opgelapt.

Io…vorrei che il giovane quando si mette a scrivere, non pensasse mai ad essere né melodista, né realista, né idealista, né avvenirista, né tutti i diavoli che si portino queste pedanterie. La melodia e l’armonia non devono essere che mezzi nella mano dell'artista per fare della Musica, e se verrà un giorno in cui non si parlerà più né di melodia né di armonia né di scuole tedesche, italiane, né di passato né di avvenire ecc. ecc. ecc. allora forse comincierà il regno dell'arte.

Jokes and their Relation to the Cognitive Unconscious (1980)
Context: All intelligent persons also possess some larger-scale frame-systems whose members seemed at first impossibly different — like water with electricity, or poetry with music. Yet many such analogies — along with the knowledge of how to apply them — are among our most powerful tools of thought. They explain our ability sometimes to see one thing — or idea — as though it were another, and thus to apply knowledge and experience gathered in one domain to solve problems in another. It is thus that we transfer knowledge via the paradigms of Science. We learn to see gases and fluids as particles, particles as waves, and waves as envelopes of growing spheres.

Notebook VII, The Chapter on Capital, pp. 628–629.
Grundrisse (1857/58)
Context: The development of fixed capital indicates in still another respect the degree of development of wealth generally, or of capital…
The creation of a large quantity of disposable time apart from necessary labour time for society generally and each of its members (i. e. room for the development of the individuals’ full productive forces, hence those of society also), this creation of not-labour time appears in the stage of capital, as of all earlier ones, as not-labour time, free time, for a few. What capital adds is that it increases the surplus labour time of the mass by all the means of art and science, because its wealth consists directly in the appropriation of surplus labour time; since value directly its purpose, not use value. It is thus, despite itself, instrumental in creating the means of social disposable time, in order to reduce labour time for the whole society to a diminishing minimum, and thus to free everyone’s time for their own development. But its tendency always, on the one side, to create disposable time, on the other, to convert it into surplus labour...
The mass of workers must themselves appropriate their own surplus labour. Once they have done so – and disposable time thereby ceases to have an antithetical existence – then, on one side, necessary labour time will be measured by the needs of the social individual, and, on the other, the development of the power of social production will grow so rapidly that, even though production is now calculated for the wealth of all, disposable time will grow for all. For real wealth is the developed productive power of all individuals. The measure of wealth is then not any longer, in any way, labour time, but rather disposable time. Labour time as the measure of value posits wealth itself as founded on poverty, and disposable time as existing in and because of the antithesis to surplus labour time; or, the positing of an individual’s entire time as labour time, and his degradation therefore to mere worker, subsumption under labour. The most developed machinery thus forces the worker to work longer than the savage does, or than he himself did with the simplest, crudest tools.

Context: Political parties exist to secure responsible government and to execute the will of the people. From these great tasks both of the old parties have turned aside. Instead of instruments to promote the general welfare they have become the tools of corrupt interests, which use them impartially to serve their selfish purposes. Behind the ostensible government sits enthroned an invisible government owing no allegiance and acknowledging no responsibility to the people. To destroy this invisible government, to dissolve the unholy alliance between corrupt business and corrupt politics, is the first task of the statesmanship of the day.

“Mass education was designed to turn independent farmers into docile, passive tools of production.”
Quotes 1990s, 1995-1999, Class Warfare, 1995
Context: Mass education was designed to turn independent farmers into docile, passive tools of production. That was its primary purpose. And don't think people didn't know it. They knew it and they fought against it. There was a lot of resistance to mass education for exactly that reason. It was also understood by the elites. Emerson once said something about how we're educating them to keep them from our throats. If you don't educate them, what we call "education," they're going to take control -- "they" being what Alexander Hamilton called the "great beast," namely the people. The anti-democratic thrust of opinion in what are called democratic societies is really ferocious. And for good reason. Because the freer the society gets, the more dangerous the great beast becomes and the more you have to be careful to cage it somehow.

2005-09, Address at Stanford University (2005)
Context: Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure — these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.

“Logic is the most useful tool of all the arts. Without it no science can be fully known.”
Summa Logicae (c. 1323), Prefatory Letter, as translated by Paul Vincent Spade (1995) http://www.pvspade.com/Logic/docs/ockham.pdf
Context: Logic is the most useful tool of all the arts. Without it no science can be fully known. It is not worn out by repeated use, after the manner of material tools, but rather admits of continual growth through the diligent exercise of any other science. For just as a mechanic who lacks a complete knowledge of his tool gains a fuller [knowledge] by using it, so one who is educated in the firm principles of logic, while he painstakingly devotes his labor to the other sciences, acquires at the same time a greater skill at this art.

Introduction
The Philosophy of Misery (1846)
Context: Tormented by conflicting feelings, I appealed to reason; and it is reason which, amid so many dogmatic contradictions, now forces the hypothesis upon me. A priori dogmatism, applying itself to God, has proved fruitless: who knows whither the hypothesis, in its turn, will lead us?
I will explain therefore how, studying in the silence of my heart, and far from every human consideration, the mystery of social revolutions, God, the great unknown, has become for me an hypothesis, — I mean a necessary dialectical tool.

“Money is only a tool in business.”
Source: My Life and Work (1922), p. 157
Context: Money is only a tool in business. It is just a part of the machinery. You might as well borrow 100,000 lathes as $100,000 if the trouble is inside your business. More lathes will not cure it; neither will more money. Only heavier doses of brains and thought and wise courage can cure. A business that misuses what it has will continue to misuse what it can get.

2013, Commencement Address at Ohio State University (May 2013)
Context: That’s precisely what the founders left us: the power to adapt to changing times. They left us the keys to a system of self-government – the tool to do big and important things together that we could not possibly do alone. To stretch railroads and electricity and a highway system across a sprawling continent. To educate our people with a system of public schools and land grant colleges, including Ohio State. To care for the sick and the vulnerable, and provide a basic level of protection from falling into abject poverty in the wealthiest nation on Earth. To conquer fascism and disease; to visit the Moon and Mars; to gradually secure our God-given rights for all our citizens, regardless of who they are, what they look like, or who they love.
We, the people, chose to do these things together. Because we know this country cannot accomplish great things if we pursue nothing greater than our own individual ambition.
Still, you’ll hear voices that incessantly warn of government as nothing more than some separate, sinister entity that’s the root of all our problems, even as they do their best to gum up the works; or that tyranny always lurks just around the corner. You should reject these voices. Because what they suggest is that our brave, creative, unique experiment in self-rule is just a sham with which we can’t be trusted.
We have never been a people who place all our faith in government to solve our problems, nor do we want it to. But we don’t think the government is the source of all our problems, either. Because we understand that this democracy is ours. As citizens, we understand that America is not about what can be done for us. It’s about what can be done by us, together, through the hard and frustrating but absolutely necessary work of self-government.
The founders trusted us with this awesome authority. We should trust ourselves with it, too. Because when we don’t, when we turn away and get discouraged and abdicate that authority, we grant our silent consent to someone who’ll gladly claim it.
