One should believe only what can be chosen to be true or just. Irrational (or unjustified) beliefs should be avoided because they can have disastrous practical consequences.

Contemporary philosophers are facing problems that were unthinkable only one century ago, such as whether space and time are mutually Independent, whether there is objective chance or only uncertainty, whether physics can explain chemical change, whether our behavior is fully determined by our genomes, whether ideation can change the brain, or whether either the economy or ideas are the ultimate roots of the social.

Under theocracies and other authoritarian regimes, the rulers are the moral authorities. Under genuine democracy some basic values are entrenched in the legal system, which is expected to be under democratic vigilance, and others are left to the person or the group, which ideally debate moral problems in a rational, free and cooperative manner.

The fact is that all the important political philosophers and scientists from the great Aristotle on, with the exception of those of the French Enlightenment and Mill, have sided with the powers that be.

I pity the babies whose mothers are busy texting trivialities instead of playing with their children; I pity the children who are tethered to their cell phones instead of playing ball; I pity the adolescents who are wasting their best years holding one of those artefacts instead of the hand of another young person.

All genuine philosophy transcends national boundaries. Patriotic philosophies are just nationalist ideologies.

Even philosophies who have denounced pseudosciences like psychoanalysis, have condoned pseudoscientific economic theories like neoclassical microeconomics. It is far safer and easier to criticize Freud and Jung than to criticize Milton Friedman and Friedrich Hayek, because the latter are backed by political movements whereas the former are not.
