It is not strange that some of our revoltes preach trial marriage: for the only safe way to marry them at all would be on trial. Until you had definitely experienced all the human situations with them, you would have no means of knowing how, in any given situation, they would behave. They might conform about evening-dress, and throw plates between courses; they might be charming to your friends, and ask the waiter to sit down and finish dinner with you. Or they might in all things, little and big, be irreproachable. The point is that you would never know.

Successful socialism depends on the perfectibility of man. Unless all, or nearly all, men are high-minded and clear-sighted, it isbound to be a rotten failure in any but a physical sense. Even through it is altruism, socialism means materialism. You can guarantee the things of the body to every one, but you cannot guarantee the things of the spirit to every one; you can guarantee only that the opportunity to seek them shall not be denied to any one who chooses to seek them.

... if we have a dollar to spend on some wild excess, we shall spend it on a book, not on asparagus out of season.

... when you make it a moral necessity for the young to dabble in all the subjects that the books on the top shelf are written about, you kill two very large birds with one stone: you satisfy precious curiosities, and you make them believe that they know as much about life as people who really know something. If college boys are solemnly advised to listen to lectures on prostitution, they will listen; and who is to blame if some time, in a less moral moment, they profit by their information?

Conventional manners are a kind of literacy test for the alien who comes among us.

... there are some who, believing that all is for the best in the best of possible worlds, and that to-morrow is necessarily better than to-day, may think that if culture is a good thing we shall infallibly be found to have more of it that we had a generation since; and that if we can be shown not to have more of it, it can be shown not to be worth seeking.
