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

A democratic state will protect the freedom to hold any beliefs other than those that harm others, such as racism. In particular, it will see to it that no one is harmed just because of her beliefs.

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

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.

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.

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

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.
