T. S. Eliot on causes

for we must know in advance, if we are prepared for that conflict, that the combat may have truces but never a peace. If we take the widest and wisest view of a Cause, there is no such thing as a Lost Cause because there is no such thing as a Gained Cause. We fight for lost causes because we know that our defeat and dismay may be the preface to our successors’ victory, though that victory itself will be temporary; we fight rather to keep something alive than in the expectation that anything will triumph.
