A distinguished cognitive neuroscientist confessed to me that, because of his religious upbringing, he could not get rid of psychoneural dualism. The idea that one ceases to be after death was too painful to him.

To me, work is not a burden but my main hobby. This is why I always take work with me when I go on holidays. Moreover, that's when new projects occur to me: while contemplating beautiful landscapes or seascapes.

One can discern a few very general myths that facilitate the birth of further myths: that everything is possible; that whatever we have failed to explain in normal and earthly terms must have paranormal or supernatural explanations; and that science, being rational, cannot explain the irrational, such as taste and love.

It occurred to me that I had the duty to give society something in exchange for the free education I was getting.

Communication accompanies social transactions and can instruct or stultify, mobilize or intimidate, but it is no substitute for production, collaboration and fight.

My Third-World roots remind me that the vast majority of our fellow human beings live hungry, sick, and uneducated, and that most social scientists, even in that world, ignore that ugly reality. This is why my papers in mathematical sociology deal not with free choice among 30 flavors of ice-cream, but with social structure, social cohesion, and social marginality.

It is scandalous the way some scientists accept uncritically some of the most ridiculous speculations, such as the plurality of worlds, the opinion that spacetime has more than 4 dimensions, that particles can move faster than light, or that human life can be prolonged indefinitely.
