T.s. Eliot said this quote
“ 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. ”
