Mankind has always drawn from outside sources of energy. This island was the first to harness coal and steam. But our present sources stand in the ratio of a million to one, compared with any previous sources. The release of atomic energy will change the whole structure of society.

An honest money system is the only alternative.

[The human control of atomic energy could] virtually provide anyone who wanted it with a private sun of his own.

I believe that there have been civilisations in the past that were familiar with atomic energy, and that by misusing it they were totally destroyed.

The dropping of the Atomic Bomb is a very deep problem... Instead of commemorating Hiroshima we should celebrate... man's triumph over the problem [of transmutation], and not its first misuse by politicians and military authorities.

Nature is in austere mood, even terrifying, withal majestically beautiful.

There is something sublime about its aloofness from and its indifference to its external environment.
