Whether the person should then be called "an intellectual" seems to reduce the issue to a question of terminology.

We are entering a period of human history that may provide an answer to the question of whether it is better to be smart than stupid.

These are questions for action, not speculation, which is idle.

There is no evolutionary pressure to create minds capable of forming sciences; it just happened. Evolutionary pressure has not led to higher rates of reproduction for people capable of solving scientific problems or creating new scientific ideas. So if, in fact, the science-forming capacities evolved for other reasons, it would not be too surprising if those particular structures that have developed proved to be rather special in their nature, reflecting the contingencies of their evolution or the working of physical law.

There was no direct way to prevent the Boston murders. There are some easy ways to prevent likely future ones: by not inciting them. That's also true of another case of a suspect murdered, his body disposed of without autopsy, when he could easily have been apprehended and brought to trial: Osama bin Laden.

In Mexico, a poor country, higher education is of quite good quality -- and is free. Ten years ago the government tried to impose small fees. There was a national student strike and the government backed down. High tuition is not an economic necessity, as is easy to show, but a debt trap is a good technique of indoctrination and control. And resisting this makes good sense.
