“The often heated and sometimes nasty debates that have taken place between gradualists and punctuationists, or between micromutationists and macromutationists, have been generated by the perception that there is only one evolutionary question, for which… there can be only one correct answer. …But if we take a different approach, and assume that both sides of a typical evolutionary debate have something valid to offer, then the theoretical and methodological disagreements between different schools of thought may just be a matter of having the right answer to a different question.”

That which is seen and that which is not seen (Ce qu'on voit et ce qu'on ne voit pas, 1850), the Introduction.
Context: In the department of economy, an act, a habit, an institution, a law, gives birth not only to an effect, but to a series of effects. Of these effects, the first only is immediate; it manifests itself simultaneously with its cause — it is seen. The others unfold in succession — they are not seen: it is well for us, if they are foreseen. Between a good and a bad economist this constitutes the whole difference: the one takes account only of the visible effect; the other takes account of both the effects which are seen and those which it is necessary to foresee. Now this difference is enormous, for it almost always happens that when the immediate consequence is favourable, the ultimate consequences are fatal, and the converse. Hence it follows that the bad economist pursues a small present good, which will be followed by a great evil to come, while the true economist pursues a great good to come, at the risk of a small present evil.
