Whenever Nature's bounty is in danger of exhaustion, the chemist has sought for a substitute. The conquest of disease has made great progress as a result of your efforts. Wherever we look, the work of the chemist has raised the level of our civilization and has increased the productive capacity of the nation.

Calvin CoolidgeNo advance, no progress can be made beyond these propositions. If anyone wishes to deny their truth or their soundness, the only direction in which he can proceed historically is not forward, but backward toward a time when there was no equality, no rights of the individual, no rule of the people. Those who wish to proceed in that direction cannot lay claim to progress. They are reactionary. Their ideas are not more modern, but more ancient than those of our Revolutionary ancestors.
