Quote

One of the extraordinary things about human events is that the unthinkable becomes thinkable.

Our thoughts and imagination are the only real limits to our possibilities.

There is nothing so unthinkable as thought, unless it be the entire absence of thought.

A lot of the things that until now seemed unthinkable are starting to be thinkable.

To achieve the impossible; it is precisely the unthinkable that must be thought.

We know it is impossible to go on finding, moving and wasting oil, leveling forests, paving land, dumping poisons, and multiplying our numbers. A new way of life, a new set of thoughts must be found.

What we learned on September 11 is that the unthinkable is now thinkable in the world.

There are thoughts we must not think.

So many of our dreams at first seem impossible, then they seem improbable, and then, when we summon the will, they soon become inevitable.

While we rejoice in the new possibilities open to humanity, we also see the dangers arising from these possibilities, and we must ask ourselves how we can overcome them.
