| The Expression Of The Emotions In Man & Animals by Charles Darwin "We can cause laughing by tickling the skin, weeping or frowning by a blow, trembling from the fear of pain, and so forth; but we cannot cause a blush... by any physical means - that it by any action on the body. It is the mind which must be affected." (page 310) "The movements of expression give vividness and energy to our spoken words. They reveal the thoughts and intentions of others more truly than do words, which may be falsified." (page 359) |
