[W]e ... know very well that we never learn unless we like our lesson, and never behave ourselves unless inspired by precept and example. The history… - Agnes Repplier

We can reckon the cost of misdirected emotions by the price which the past has paid for them. We know the full significance of that irresponsible sympathy which ... admits no difference between attack and resistance, between a war of aggression and a war of defence; which confuses moral issues, ignores experience, and insults the intelligence of mankind. The reformer whose heart is in the right place, but whose head is elsewhere, represents a waste of force; and we can not afford any waste in the conservation of honour and goodness.

War will pass when injustice passes. Never before, unless hope leaves the world.

The sentiment of to-day is social and philanthropic. ... [but] we must forever bear in mind that sentiment is subjective, and a personal thing. However exalted and however ardent, it cannot be accepted as a scale for justice, or as a test for truth.
