The idealist's program of political or economic reform may be impracticable, absurd, demonstrably ridiculous; but it can never be successfully opposed merely by pointing out that this is the case. A negative opposition cannot be wholly effectual: there must be a competing idealism; something must be offered that is not only less objectionable but more desirable.

Summary

This quote highlights the importance of constructive criticism and offering alternative solutions. It suggests that simply dismissing or criticizing an idealist's impracticable reform ideas is not enough. To effectively confront and counter these ideas, one must present a different but more attractive idealism, providing an alternative that is both less objectionable and more desirable. The quote encourages a positive engagement in opposition, emphasizing the need for practical alternatives rather than a mere rejection of unrealistic proposals.
