“When the act of navigation was made, though England and Holland were not actually at war, the most violent animosity subsisted between the two nations. … It is not impossible, therefore, that some of the regulations of this famous act may have proceeded from national animosity. They are as wise, however, as if they had all been dictated by the most deliberate wisdom. National animosity at that particular time aimed at the very same object which the most deliberate wisdom would have recommended, the diminution of the naval power of Holland, the only naval power which could endanger the security of England.”

Quotes, The Assault on Reason (2007)
Context: History will surely judge America's decision to invade and occupy a fragile and unstable nation that did not attack us and posed no threat to us as a decision that was not only tragic but absurd. Saddam Hussein was a brutal dictator, to be sure, but not one who posed an imminent danger to us. It is a decision that could have been made only at a moment in time when reason was playing a sharply diminished role in our national deliberations.

Context: It is useless to try to adjudicate a long-standing animosity by asking who started it or who is the most wrong. The only sufficient answer is to give up the animosity and try forgiveness, to try to love our enemies and to talk to them and (if we pray) to pray for them. If we can't do any of that, then we must begin again by trying to imagine our enemies' children who, like our children, are in mortal danger because of enmity that they did not cause.

A View of the Internal Evidence of the Christian Religion (1776), p. 47

Natürlich ist es im Interesse des Handelnden, mit dem einen, von welchem er wohlfeil kauft, wie mit dem andern, an welchen er teuer verkauft, sich in gutem Vernehmen zu halten. Es ist also sehr unklug von einer Nation gehandelt, wenn sie bei ihren Versorgern und Kunden eine feindselige Stimmung nährt. Je freundschaftlicher, desto vorteilhafter. Dies ist die Humanität des Handels, und diese gleisnerische Art, die Sittlichkeit zu unsittlichen Zwecken zu mißbrauchen, ist der Stolz des Systems der Handelsfreiheit.
