Quotes from the same author

While I complain of being able to glimpse no more than the shadow of the past, I may be insensitive to reality as it is taking shape at this very moment, since I have not reached the stage of development at which I would be capable of perceiving it. A few hundred years hence, in this same place, another traveller, as despairing as myself, will mourn the disappearance of what I might have seen, but failed to see.

Freedom is neither a legal invention nor a philosophical conquest, the cherished possession of civilizations more valid than others because they alone have been able to create or preserve it.

Nor must we forget that in science there are no final truths.
