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.

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.

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.

I believe that modern science supports free will, in showing that the brain can act spontaneously, not only in response to external stimuli.

Some of the big philosophical problems have been solved by science, at least to a 1st approximation. Examples: the problems of matter, and mind. Only philosophical reactionaries, like Noam Chomsky, claim that they are and will remain mysteries.

From a historical viewpoint, religion is just a kind of superstition, and from a political viewpoint it is a tool of social control.

Of course much remains to know, but we know how to learn: through scientific research.
