In general, we look for a new law by the following process: First we guess it. Then we – now don't laugh, that's really true. Then we compute the consequences of the guess to see what, if this is right, if this law that we guessed is right, to see what it would imply. And then we compare the computation results to nature, or we say compare to experiment or experience, compare it directly with observations to see if it works. If it disagrees with experiment, it's wrong. In that simple statement is the key to science. It doesn't make any difference how beautiful your guess is, it doesn't make any difference how smart you are, who made the guess, or what his name is. If it disagrees with experiment, it's wrong. That's all there is to it.

We must now try to sum up, to draw together the threads of what has been said above on the subject of imperialism. Imperialism emerged as the development and direct continuation of the fundamental characteristics of capitalism in general. But capitalism only became capitalist imperialism at a definite and very high stage of its development, when certain of its fundamental characteristics began to change into their opposites, when the features of the epoch of transition from capitalism to a higher social and economic system had taken shape and revealed themselves in all spheres. Economically, the main thing in this process is the displacement of capitalist free competition by capitalist monopoly.
Vladimir Lenin
This idea is that laws which purport to be statements of what actually occurs are statistical in character as distinct from so-called dynamic laws that are abstract and mathematical, and disguised definitions. Recognition of the statistical nature of physical laws was first effected in the case of gases when it became evident that generalizations regarding the behavior of swarms of molecules were not descriptions or predictions of the behavior of any individual particle. A single molecule is not and cannot be a gas. It is consequently absurd to suppose that a scientific law is about the elementary constituents of a gas. It is a statement of what happens when a large number of such constituents interact with one another under certain conditions.

I always felt, in looking at [the Cuban] situation, that it was wrong. And I now know why. It came to me one night in Mexico. China is communist, the same as Cuba, and yet we have no problem trading with China. In fact, today we can't get over there quick enough. The difference is simple: China welcomes our corporations. Cuba threw them out. It's a basic decision of corporate America: We will punish Cuba because Castro stuck it to us by nationalizing everything after he came to power. What other reason could there be? China is far more powerful but we now welcome them into global trade with open arms-as we should-while we continue this bitter, hostile policy towards Cuba. It must be because there are still people alive in the corporate world who got hammered by Fidel's revolution.

I well remember receiving from one of the most earnest of my seniors the friendly warning that it was waste of time to study variation, for "Darwin had swept the field." Parenthetically we may notice that though scientific opinion in general became rapidly converted to the doctrine of pure selection, there was one remarkable exception. Systematists for the most part kept aloof. Everyone was convinced that natural selection operating in a continuously varying population was a sufficient account of the origin of species except the one class of scientific workers whose labours familiarised them with the phenomenon of specific difference. From that time the systematists became, as they still in great measure remain, a class apart.
William Bateson
Racism is evil -- and those who cause violence in its name are criminals and thugs, including KKK, neo-Nazis, white supremacists, and other hate groups are repugnant to everything we hold dear as Americans. Those who spread violence in the name of bigotry strike at the very core of America. As a candidate I promised to restore law and order to our country and our federal law enforcement agencies are following through on that pledge. We will spare no resource in fighting so that every American child can grow up free from violence and fear. We will defend and protect the sacred rights of all Americans and we will work together so that every citizen in this blessed land is free to follow their dreams, in their hearts, and to express the love and joy in our souls.
