Passos vs. Saltos
[1] Brian Weatherson, What good are counterexamples (2003)
Morrerás em breve. É incontestável. E quanta verdade morrerá contigo sem saberes que a sabias. Só por não teres tido a sorte de num simples encontro ou encontrão ta fazerem vir ao de cima - Vergílio Ferreira

"When people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together." The Relativity of Wrong, Isaac AsimovThe Sophisticate: The world isn't black and white. No one does pure good or pure bad. It's all gray. Therefore, no one is better than anyone else.
The Zetet: Knowing only gray, you conclude that all grays are the same shade. You mock the simplicity of the two-color view, yet you replace it with a one-color view... - David's Sling, Marc Stiegler

"Humans are very good as seeing patterns, making connections, and coming up with explanations for phenomena. Almost anything can be explained in retrospect, and it only takes a couple of apparent connections to make such explanations seem compelling. That is actually the fatal flaw of such post-hoc reasoning – it can be used to explain anything. Therefore, the fact that someone can invent a post-hoc justification is not predictive that the explanation is actually true. In other words – we tend to be naively impressed with the fact that an explanation is available. We tend to assume that a phenomenon would not have an explanation, or alternative explanation, if that explanation were not true. We therefore find it satisfying, and therefore compelling, when such an explanation is available. However, the human capacity for invention and pattern seeking is profound. We can find an explanation for anything – and so the availability of such an explanation should not be compelling at all." - Juicy Post-Hoc Reasoning, Steven Novella

"The way the US patent system is currently set up, it’s difficult if not impossible to write a sizable body of code without unknowingly infringing on somebody’s patent. Your best hope seems to be to waste a lot of time filing as many patents as you can of your own, and hoping that anybody who sues you is unknowingly infringing on one of yours. That gives you a bargaining chip so you can do some kind of cross licensing deal. It’s a stupid, wasteful, unproductive government-created system that achieves the exact opposite of what was intended when it was first started. But, what can you do." - Ed Burnette

"What is meant by the word red?"
"It's a color."
"What's a color?"
"Why, it's a quality things have."
"What's a quality?"
"Say, what are you trying to do, anyway?"You have pushed him into the clouds. If, on the other hand, we habitually go down the abstraction ladder to lower levels of abstraction when we are asked the meaning of a word, we are less likely to get lost in verbal mazes; we will tend to "have our feet on the ground" and know what we are talking about. This habit displays itself in an answer such as this:
"What is meant by the word red?"
"Well, the next time you see some cars stopped at an intersection, look at the traffic light facing them. Also, you might go to the fire department and see how their trucks are painted."-- S. I. Hayakawa, Language in Thought and Action [via Less Wrong]

"Imagine a language in which, instead of saying ‘I found nobody in the room’ one said, ‘I found Mr. Nobody in the room.’ Imagine the philosophical problems that would arise out of such a convention." Wittgenstein, The Blue Book

[O]nly because scarcity exists is there even a problem of formulating moral laws; insofar as goods are superabundant (“free” goods), no conflict over the use of goods is possible and no action-coordination is needed. Hence, it follows that any ethic, correctly conceived, must be formulated as a theory of property, i.e., a theory of the as signment of rights of exclusive control over scarce means. Because only then does it become possible to avoid otherwise inescapable and unresolvable conflict.
