While Nietzsche's quote that 'there are no eternal facts' has been
appropriated by relativists, this statement is entirely consistent with
our Popperian approach to truth today: we hold on to truths before new
evidence comes along to prove otherwise....
Nietzsche was in the end a radical empiricist — a self-declared enemy of
ideology, ideologues and people who cling dogmatically to systems,
beliefs and '-isms'.
