It is progress when a centuries-old oak is cut down to give space for a road sign.

I also believe that when one dies, one may wake up to the reality that proves that time does not exist.

I don't believe in war as a solution to any kind of conflict, nor do I believe in heroism on the battlefield because I have never seen any.

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.

It is progress when weapons are improved to kill more people at a longer range.

But if we begin thinking about the world being over 100 million years old, then it's absolutely by chance that you and I are sitting here alive today, while all the others are dead or have never been born.

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.
