Philosophy can be compared to some powders that are so corrosive that, after they have eaten away the infected flesh of a wound, they then devour the living flesh, rot the bones, and penetrate to the very marrow.

And when it is left on its own, it goes so far that it no longer knows where it is and can find no stopping place.

I know of nothing which hangs so ill together! To offer such things in seriousness, shows the greatest contempt of mankind, and the most scandalous lying impunity.

It is pure illusion to think that an opinion which passes down from century to century, from generation to generation, may not be entirely false.

I know too much to be a sceptic and too little to be a dogmatist.
