Civilization grew in the beginning from the minute that we had communication - particularly communication by sea that enabled people to get inspiration and ideas from each other and to exchange basic raw materials.

In my experience, it is rarer to find a really happy person in a circle of millionaires than among vagabonds.

It is also rarer to find happiness in a man surrounded by the miracles of technology than among people living in the desert of the jungle and who by the standards set by our society would be considered destitute and out of touch.

For every minute, the future is becoming the past.

I have never been able to grasp the meaning of time. I don't believe it exists. I've felt this again and again, when alone and out in nature. On such occasions, time does not exist. Nor does the future exist.

I was in uniform for four years, and I know that heroism doesn't occur from taking orders, but rather from people who through their own willpower and strength are willing to sacrifice their lives for an idea.

Progress is man's ability to complicate simplicity.
