Our technological powers increase but the side effects and potential hazards also escalate.

This is just what I have thought when I have seen slaves at work - they seem to go through the motions of labor without putting strength into them. They keep their powers in reserve for their own use at night perhaps.

The colour of the skin is in no way connected with strength of the mind or intellectual powers.

Because your own strength is unequal to the task do not assume that it is beyond the powers of man but if anything is within the powers and province of man believe that it is within your own compass also.

Society has to change but the political powers we have at the moment are not enough to effect this change. The whole democratic system would have to be rethought.

I know of no safe depository of the ultimate powers of the society but the people themselves and if we think them not enlightened enough to exercise their control with a wholesome discretion the remedy is not to take it from them but to inform their discretion.

In the last fifty years science has advanced more than in the 2 000 previous years and given mankind greater powers over the forces of nature than the ancients ascribed to their gods.

Science has produced such powerful weapons that in a war between great powers there would be neither victor nor vanquished. Both would be overwhelmed in destruction.

Awaken its powers and it will respect itself.

We never respect those who amuse us however we may smile at their comic powers.
