There are huge areas where the human mind is apparently incapable of forming sciences, or at least has not done so. There are other areas - so far, in fact, one area only [physics] - in which we have demonstrated the capacity for true scientific progress.

To construct a scientific theory from the data and to be able to recognize that it is a reasonable theory is possible only if there are some very sharp restrictive principles that lead you to go in one direction and not in another direction. Otherwise, you wouldn't have science at all, merely randomly chosen hypotheses.

Where are the drug cartels getting their weapons? They are being provided by the United States. Cut off that flow of arms.

Government grew under [Ronald] Reagan. He was the strongest opponent of free markets in the post-war history among presidents. But it doesn't matter what the reality is; they concocted an image that you worship.

People who spend their working hours in a lab or research library or a classroom might be intent primarily on keeping or advancing their elite positions, thereby lending tacit support to power structures. Or they might not be.

Through much of its history, the US did not have high inequality as compared with Europe. Less so, in fact. That began to change in the industrial age, reaching a peak in 1928, after the forceful destruction of the labor movement and crushing of independent thought. Largely as a result of labor mobilization, inequality declined during the Great Depression, a tendency continuing through the great growth period of regulated capitalism in the early postwar decades.

Venezuela is independent. It's diversifying its exports to a limited extent, instead of just being dependent on exports to the United States. And it's initiating moves toward Latin American integration and independence. It's what they call a Bolivarian alternative and the United States doesn't like any of that.
