We said, there's another second gone, there's another minute and another hour and another day, when, as a matter of fact the second or the minute or the hour was never gone. It was the same one all the time. It had just moved along and we had moved with it.

Time is still the great mystery to us. It is no more than a concept; we don't know if it even exists.

If mankind were to continue in other than the present barbarism, a new path must be found, a new civilization based on some other method than technology.
