Freezing concentrates sugar (maple sugar), alcohol, and salt solutions as efficiently as heating distils water or alcohol from solutions. Open pans of maple sugar can have the surface ice removed regularly (each day) until a sugar concentrate remains. Salts in water, and alcohol in ferment liquors can be concentrated in the same way.

Anything that's left that's remotely like wilderness should be left strictly alone. We have no business there any more. It's not going to save you to go in and cut the last old-stand forests.

I think we probably have a racial death wish. We don't understand anything about where we live, and we don't want to.

Why is it that we don't build human settlements that will feed themselves, and fuel themselves, and catch their own water, when any human settlement could do that easily? When it's a trivial thing to do?

I could never teach people to be philosophers - and if I did, you could never make a gardener out of them.

Few people today muck around in earth, and when on international flights, I often find I have the only decently dirty fingernails.

I can easily teach people to be gardeners, and from them, once they know how to garden, you'll get a philosopher.
