“Wind is lord and change is sovereign of the strand.”

This is how the spirit comes. After the gale, the earthquake, and fire: a gentle, cooling breeze. This is how it will come in our own day as well. We are passing through the period of earthquake, the fire is approaching, and eventually (when? after how many generations?) the gentle, cool breeze will blow.

Context: The most striking of all the impressions I have formed since I left London a month ago is of the strength of this African national consciousness. In different places it may take different forms but it is happening everywhere. The wind of change is blowing through this continent. Whether we like it or not, this growth of national consciousness is a political fact. We must all accept it as a fact.

1860s, First Inaugural Address (1861)
Context: Plainly, the central idea of secession is the essence of anarchy. A majority held in restraint by constitutional checks and limitations, and always changing easily with deliberate changes of popular opinions and sentiments, is the only true sovereign of a free people. Whoever rejects it does, of necessity, fly to anarchy or to despotism. Unanimity is impossible; the rule of a minority, as a permanent arrangement, is wholly inadmissible; so that, rejecting the majority principle, anarchy or despotism in some form is all that is left.
