"The phenomenon develops calmly, but it is invisible, unstoppable. One feels, one sees it born and grow steadily; and it is not in one's power to either hasten or slow it down"

The quote by Leon Foucault discusses a phenomenon that grows progressively and unstoppably, with no external influence to quicken or slow it down. The development of this phenomenon is serene and unnoticeable, yet its existence can be felt and perceived by those who observe it. The text suggests that human beings are mere witnesses to the unstoppable progress of nature and science, which they have no control over the course of occasions that unfold. The quote suggests that we need to accept the natural order of things and trust the course of events to take their own path, without attempting to artificially manipulate or control them.
