Not Nostradamus

Brad DeLong still wants the attempted extrapolation of trends to be equivalent to prophecy. So I thought I'd point out another nineteenth century writer:

"There are at the present time two great nations in the world, which started from different points, but seem to tend towards the same end. I allude to the Russians and the Americans. Both of them have grown up unnoticed; and while the attention of mankind was directed elsewhere, they have suddenly placed themselves in the front rank among the nations, and the world learned their existence and their greatness at almost the same time.

All other nations seem to have nearly reached their natural limits, and they have only to maintain their power; but these are still in the act of growth. All others have stopped, or continue to advance with extreme difficulty; these alone are proceeding with ease and celerity along a path to which no limit can be perceived. The American struggles against the obstacles that nature opposes to him; the adversaries of the Russian are men. The former combats the wilderness and savage life; the latter, civilization with all its arms. The conquests of the American are therefore gained by the plowshare; those of the Russian by the sword. The Anglo-American relies upon personal interest to accomplish his ends and gives free scope to the unguided strength and common sense of the people; the Russian centers all the authority of society in a single arm. The principal instrument of the former is freedom; of the latter, servitude. Their starting point is different and their courses are not the same; yet each seems marked out by the will of Heaven to sway the destinities of half the globe." -- Alexis de Tocqueville, Democracy in America, V. 1, last page
