Saith Robin in "Seeking a Cynic's Library":

Cynicism and Idealism are a classic yin and yang, a contradictory pair where we all seem to need both sides...

Books on education, medicine, government, charity, religion, technology, travel, relationships, etc. mostly present relatively idealistic views, though of course no view is entirely one way or the other. So one reason the young tend to be idealistic is that most reading material they can easily find and understand is idealistic.

My impression of this differs somewhat from Robin's (what a surprise).

I think that what we see in most books of the class Robin describes, are official views. These official views may leave out many unpleasant elements of the story. But because officialism also tries to signal authority and maturity, it's hardly likely to permit itself any real hope or enthusiasm. Perhaps an obligatory if formal nod in the direction of some popular good cause, because this is expected of officialdom. But this is hardly an idealistic voice.

What does a full-blown nonfictional idealism look like? Some examples that I remember from my own youth:

Jerry Pournelle's A Step Farther Out, an idealistic view of space travel and more general technological advancement, and the possibility of rising standards of living as opposed to Ehrlichian gloomsaying.
Brown, Keating, Mellinger, Post, Smith, and Tudor's The Incredible Bread Machine, my childhood introduction to traditional capitalist values.
Eric Drexler's Engines of Creation (and to a lesser extent Ed Regis's Great Mambo Chicken), my introduction to transhumanism.
Richard Feynman's Surely You're Joking, Mr. Feynman (for traditional rationalist values).

Supposing you wanted your child to grow up an idealist - what nonfiction books like these could you find to give them? I don't find it easy to think of many - most nonfiction books are not like this.

On the other hand, I suspect that idealistic fiction aimed specifically at children is a far greater cultural force than anything they pick up from their school textbooks. Textbooks are marketed to adult textbook-selectors; juvenile fiction and children's television are actually aimed at children.

Of course this just implies a chicken-and-egg problem; why do children enjoy idealism more than cynicism...
