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.
Mario BungeAll genuine philosophy transcends national boundaries. Patriotic philosophies are just nationalist ideologies.
Mario BungeEven 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.
Mario BungeContemporary 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.
Mario BungeIn any event, I don't believe in instant philosophy, because interesting problems take a long time to understand and work out. Just think of the problems of truth and justice.
Mario BungeUnder 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.
