The development of space technology, including space warfare today, is similar in its technological-industrial significance to the development of navies a hundred years ago.

The US and Canada are now increasingly isolated in the hemisphere, and sooner or later, I think we're going to find that the US and Canada are simply excluded from hemispheric affairs. That's a sharp reversal of what was the case not long ago.

I don't think there is any scientific evidence about the question of whether we think only in language or not. But introspection indicates pretty clearly that we don't think in language necessarily. We also think in visual images, we think in terms of situations and events, and so on, and many times we can't even express in words what the content of our thinking is. And even if we are able to express it in words, it is a common experience to say something and then to recognize that it is not what we meant, that it is something else.

The Democrats have pretty much given up on the white working class. That would require a commitment to economic issues and that's not their concern.

In the literal sense, there has been no relevant evolution since the trek from Africa. But there has been substantial progress towards higher standards of rights, justice and freedom - along with all too many illustrations of how remote is the goal of a decent society.

Those who wish to change the world should have the best possible understanding of the world, including what is revealed by the sciences, some of which they might be able to use for their purposes. That's why workers education, including science and mathematics, has commonly been a concern of left intellectuals.

My feeling is that a human being or any complex organism has a system of cognitive structures that develop much in the way the physical organs of the body develop. That is, in their fundamental character they are innate; their basic form is determined by the genetic structure of the organism. Of course, they grow under particular environmental conditions, assuming a specific form that admits of some variation. Much of what is distinctive among human beings is a specific manner in which a variety of shared cognitive structures develop.
