“Facts and events are infinitely more fragile things than axioms, discoveries, theories – even the most wildly specula-tive ones – produced by the human mind; they occur in the field of the ever-changing affairs of men, in whose flux there is nothing more perma-nent than the admi-ttedly relative perma-nence of the human mind’s structure. Once they are lost, no rational effort will ever bring them back.”
