I do not think that, practically or morally, we can defend a policy of saving every distinctive local population of organisms. I can cite a good rationale for the preservation of species, for each species is a unique and separate natural object that, once lost, can never be reconstituted. But subspecies are distinctive local populations of species with broader geographic range. Subspecies are dynamic, interbreedable, and constantly changing: what then are we saving by declaring them all inviolate?

Most English speakers do not have the writer's short fuse about seeing or hearing their language brutalized. This is the main reason, I suspect, that English is becoming the world's universal tongue: English-speaking natives don't care how badly others speak English as long as they speak it. French, once considered likely to become the world's lingua franca, has lost popularity because those who are born speaking it reject this liberal attitude and become depressed, insulted or insufferable when their language is ill used.

My reluctance to use alien invasion is due to the feeling that we are not likely to be invaded and taken over. It would seem to me that by the time a race has achieved deep space capability it would have matured to a point where it would have no thought of dominating another intelligent species. Further than this, there should be no economic necessity of its doing so. By the time it was able to go into deep space, it must have arrived at an energy source which would not be based on planetary natural resources.

At this point in history when all things which concern man and the structure and elements of history itself are suddenly revealed to us in a new light, it behooves us in our scientific thinking to become masters of the situation, for it is not inconceivable that sooner than we suspect, as has often been the case before in history, this vision may disappear, the opportunity may be lost, and the world will once again present a static, uniform, and inflexible countenance.
Karl Mannheim
Superficial knowledge ... is hurtful to those who possess true genius; for it necessarily draws them away from their main object, wastes their industry over details and subjects foreign to their needs and natural talent, and lastly does not serve, as they flatter themselves, to prove the breadth of their mind. In all ages there have been men of very moderate intelligence who knew much, and so on the contrary, men of the highest intelligence who knew very little. Ignorance is not lack of intelligence, nor knowledge a proof of genius.
Luc de Clapiers, Marquis de Vauvenargues
Never mind failures; they are quite natural, they are the beauty of life, these failures. What would life be without them? It would not be worth having if it were not for struggles. Where would be the poetry of life? Never mind the struggles, the mistakes. I never heard a cow tell a lie, but it is only a cow-never a man. So never mind these failures, these little backslidings; hold the ideal a thousand times, and if you fail a thousand times, make the attempt once more.
