Animal behavior has evolved to battle parasites. In fact, we have parasites to thank for the existence of sex. Sex is a costly and time-consuming method of reproduction. Experiments have shown that, in the absence of parasites, species evolve toward parthenogenesis-or cloning-as the reproductive method of choice. In parthenogenesis each individual is able to self-replicate. But this produces almost no genetic variation. In the presence of parasites, cloning, while more energy-efficient, is not a viable reproductive strategy. It presents a stationary genetic target to parasites, who, once introduced into such a system, will quickly dominate it. ...

A mental shortcut becomes almost irresistible and maybe even rational by some lights. The two young black men on one side of the street look like so many others the officer has locked up. Two white men on the other side of the street-even in the same clothes-do not. The officer does not make the same association about the two white guys, whether that officer is white or black. And that drives different behavior. The officer turns toward one side of the street and not the other. We need to come to grips with the fact that this behavior complicates the relationship between police and the communities they serve.

Thank you for your kind invitation. As someone who has enjoyed visiting Russia in the past and can also claim a degree of Russian ancestry, it would make me happy to say yes. However, as a gay man, I must decline. I am deeply troubled by the current attitude toward and treatment of gay men and women by the Russian government. The situation is in no way acceptable, and I cannot in good conscience participate in a celebratory occasion hosted by a country where people like myself are being systematically denied their basic right to live and love openly. Perhaps, when and if circumstances improve, I'll be free to make a different choice.

It rained. The procession of weary soldiers became a bedraggled train, despondent and muttering, marching with churning effort in a trough of liquid brown mud under a low, wretched sky. Yet the youth smiled, for he saw that the world was a world for him, though many discovered it to be made of oaths and walking sticks. He had rid himself of the red sickness of battle. The sultry nightmare was in the past. He had been an animal blistered and sweating in the heat and pain of war. He turned now with a lover's thirst to images of tranquil skies, fresh meadows, cool brooks - an existence of soft and eternal peace.
Over the river a golden ray of sun came through the hosts of leaden rain clouds.

Firstly what does conservation mean? It is not merely the saving from extinction of such species as the Notornis, the Leadbetters Possum or the Leathery Turtle; this is important work but it is only part of the problem. You cannot begin to preserve any species of animal unless you preserve the habitat in which it dwells. Disturb or destroy that habitat and you will exterminate the species as surely as if you had shot it. So conservation means that you have to preserve forest and grassland, river and lake, even the sea itself. This is not only vital for the preservation of animal life generally, but for the future existence of man himself - a point that seems to escape many people.

We might as well hope for the termination of the struggle for existence by which, some philosophers tell us, the existence or the modification of the various species of organized beings upon our planet are determined. The battle for political power is merely an effort, well or ill-judged, on the part of the classes who wage it to better or to secure their own position. Unless our social activity shall have become paralyzed, and the nation shall have lost its vitality, this battle must continue to rage. In this sense the question of reform, that is to say, the question of relative class power, can never be settled.
