Now, among the heresies that are spoken in this matter is the habit of calling a grey day a "colourless" day. Grey is a colour, and can be a very powerful and pleasing colour.... A grey clouded sky is indeed a canopy between us and the sun; so is a green tree, if it comes to that. But the grey umbrellas differ as much as the green in their style and shape, in their tint and tilt. One day may be grey like steel, and another grey like dove’s plumage. One may seem grey like the deathly frost, and another grey like the smoke of substantial kitchens.

Without enough wilderness America will change. Democracy, with its myriad personalities and increasing sophistication, must be fibred and vitalized by regular contact with outdoor growths - animals, trees, sun warmth and free skies - or it will dwindle and pale.
Oh, what a glory doth this world put on, for him who with a fervent heart goes forth under the bright and glorious sky, and looks on duties well performed, and days well spent.

Both the President and Mr Gorbachev have said that they want to see a world without nuclear weapons. I cannot see a world without nuclear weapons. Let me be practical about it. The knowledge is there to make them. So do not go too hard for that pie in the sky because, while everyone would like to see it, I do not believe it is going to come about.
If we're going to prevent large parts of this Earth from becoming not only inhospitable but uninhabitable in our lifetimes, we're going to have to keep some fossil fuels in the ground rather than burn them and release more dangerous pollution into the sky.
