1. “… a willingness to pursue and argument to its conclusion, challenging it at every stage and seeing it always open to refutation…involves a double commitment; first a commitment to the truth (the point of rejecting arguments which can be shown to be false…); secondly, commitment to certain moral values implicit in such a method; honesty, openness and impartiality – terms which inescapably lead to some notion of moral right, justice or moral good.”
Brenda Almond, Exploring Philosophy

2. “From the earliest time of my studies I set up for myself the rule that whenever I discern a sounder opinion in any matter whatsoever, I gladly and humbly abandon the earlier one; for I know that those things that I have learned are but in the least in comparison to what I do not know.” Jan Hus, 14th C.
