“Reason without emotion is often a mask for cruelty; emotion without reason can allow people to excuse all sorts of excesses.”

“Emotion without reason lets people walk all over you; reason without emotion is a mask for cruelty.”

“Were we incapable of empathy – of putting ourselves in the position of others and seeing that their suffering is like our own – then ethical reasoning would lead nowhere. If emotion without reason is blind, then reason without emotion is impotent.”

“Human beings sometimes find a kind of pleasure in nursing painful emotions, in blaming themselves without reason or even against reason.”

“Faces may be hard to read because humans are complex social animals that have learned to suppress the display of emotions for various reasons. It is often inappropriate to show negative emotions like hatred and contempt in public, so people go about wearing socially acceptable faces rather like masks.”

“No emotion is, in itself, a judgement; in that sense all emotions and sentiments are alogical. but they can be reasonable or unreasonable as they conform to Reason or fail to conform. The heart never takes the place of the head: but it can, and should, obey it.”
