The subject of emotions is probably the most universal one and yet can at times be a uniquely controversial one. We all emote. We all feel emotions. Some perhaps more strongly than others. But it is a tough thing to measure. And emotions are not unique to humans alone. Affection, fear, joy, lust, sorrow, excitement. Nearly all members of the animal kingdom experience emotions. What is perhaps unique to the human being is the ability to cognitively recognise our emotions and analyse the effects they have on us.
