It seems clear to me that marriage ought to be constituted by children, and relations not involving children ought to be ignored by the law and treated as indifferent by public opinion. It is only through children that relations cease to be a purely private matter.
It is possible that mankind is on the threshold of a golden age; but, if so, it will be necessary first to slay the dragon that guards the door, and this dragon is religion.

It is feared that if many H-bombs are used there will be universal death, sudden only for a minority, but for the majority a slow torture of disease and disintegration.
It cannot be denied that tact is a virtue. The sort of person who always manages to blurt out the tactless thing, apparently by accident, is a person full of dislike of his or her fellow creatures. But although tact is a virtue, it is very closely allied to certain vices; the line between tact and hypocrisy is a very narrow one. I think the distinction comes in the motive: when it is kindliness that makes us wish to please, our tact is the right sort; when it is fear of offending, or desire to obtain some advantage by flattery, our tact is apt to be of a less amiable kind.
