1520: Ferdinand Magellan enters the narrow strait that now bears his name. While not as navigationally straightforward as the route around Cape Horn, and it avoids the ferocious westerlies and high sea states of the Horn passage.

1790: British author and political philosopher Edmund Burke publishes his letter, Reflections on the Revolution in France, in which he examines the French body politic and its leadership through the lens of the same Natural Law that guided the original revolution in the former British colonies. Burke argues that the abstract foundations of the French revolution could not account for the complexity of human nature, and the enterprise was doomed to lead to tyranny. Critical of the rule of intellectuals, and pointing out the dangers, “What is the use of discussing a man’s abstract right to food or to medicine? The question is upon the method of procuring and administering them. In this deliberation I shall always advise to call in the aid of the farmer and the physician, rather than the professor.”
