Isaac Asimov Robot Quotations

A robot may not injure a human being, or, through inaction, allow a human being to come to harm.

A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

Since emotions are few and reasons are many (said the robot Giscard) the behavior of a crowd can be more easily predicted than the behavior of one person.

Robots will neither be common nor very good in 2014, but they will be in existence.

... you just can't differentiate between a robot and the very best of humans.
