Nations are not ruined by one act of violence, but gradually and in an almost imperceptible manner by the depreciation of their circulating currency, through its excessive quantity.
Interpretation
Nations decline gradually due to economic instability rather than through single acts of aggression.
Copernicus implies that the downfall of nations is often subtle and insidious, primarily driven by the devaluation of currency caused by overproduction. This highlights the fragility of economic systems and the importance of maintaining a stable currency to ensure the health and longevity of a nation.
In practice
In a speech about economic policy, one might say, 'As Copernicus noted, nations are not destroyed overnight but through gradual economic decline.'
So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.
So if the worth of the arts were measured by the matter with which they deal, this art-which some call astronomy, others astrology, and many of the ancients the consummation of mathematics-would be by far the most outstanding. This art which is as it were the head of all the liberal arts and the one most worthy of a free man leans upon nearly all the other branches of mathe matics. Arithmetic, geometry, optics, geodesy, mechanics, and whatever others, all offer themselves in its service.
Those who know that the consensus of many centuries has sanctioned the conception that the earth remains at rest in the middle of the heavens as its center, would, I reflected, regard it as an insane pronouncement if I made the opposite assertion that the earth moves.
The strongest affection and utmost zeal should, I think, promote the studies concerned with the most beautiful objects, most deserving to be known.
The massive bulk of the earth does indeed shrink to insignificance in comparison with the size of the heavens.
So, influenced by these advisors and this hope, I have at length allowed my friends to publish the work, as they had long besought me to do.
Man... knows only when he is satisfied and when he suffers, and only his sufferings and his satisfactions instruct him concerning himself, teach him what to seek and what to avoid. For the rest, man is a confused creature; he knows not whence he comes or whither he goes, he knows little of the world, and above all, he knows little of himself.
So the blind will lead the blind, and the deaf shout warnings to one another until their voices are lost.
The Land of Israel will be small, but the people of Israel will make it great. Not _x000D_ in opulence, but in eminence will their destiny be fulfilled, and the elixir of their_x000D_ pride will be distilled not out of dominion or far-flung borders, but out of the_x000D_ faithful and skillful building of the good society.
Gender is the poetry each of us makes out of the language we are taught.
At no point in history have so many non-risk-takers, that is, those with no personal exposure, exerted so much control.
When the mask of self-righteousness has been torn from us and we stand stripped of all our accustomed defenses, we are candidates for God's generous grace.
