"There is an almost universal tendency,
perhaps an inborn tendency,
to suspect the good faith of a man
who holds opinions that differ from our own opinions...
It obviously endangers the freedom
and the objectivity of our discussion
if we attack a person instead of attacking
an opinion or, more precisely, a theory."
Sir Karl Popper
(1902-1993) Austrian-born British philosopher, academic and social commentator
“The Importance of Critical Discussion,” in On The Barricades, 1989
