I have often wondered about why people fall in love. And, I have been told that unlike in animals, humans look for more than sex. They redefine sex as sexuality, that is, one's sexual abilities are recast as constituents of one's identity. One dresses 'up', one looks 'pretty', one is 'coy' and a host of other things. Soon even in non-sexual spaces, one gets an opportunity to express ones 'mating' behaviour. This leads to attraction and courtship and soon what is primarily sexual becomes socio-cultural. The institution of marriage is an excellent case in point. Therefore, people talk of the sense of humour, honesty, intelligence and a host of non-sexual attributes as the criterion for loving each other. In banal terms, we call them 'turn ons'. Why do we hunt for these attributes? Are we too embarrassed to admit our primary drives? Are they absolutely irrelevant in the course of 'falling in love'? I guess not.
Over a period of time human activities expand beyond hunting and gathering food, cooking, nursing family and procreating. With resources, machines and civilization we have leisure and activities that fill up our leisure. We read, watch plays, paint, play games and talk and listen to each other. Increasingly, these activities assume significance in our lives and they inform our 'basic' activities.
Soon, we replace eating and food with the notion of 'cuisine', 'work' increasingly incorporates 'play' and sex is aestheticised in art. As all of this happens, 'love' becomes a complicated affair. Or, we pretend that what is basic to be evolved!
I think we need to re-phrase the question? What sustains happiness between two people when they do not procreate? Many relationships break because people do not focus on being happy in togetherness. Instead, we build our own fairy castles in the air and look for their realization through others. Love becomes the oppressive heat of May.
Where is the love that we have lost to living, to honeymoons, fine-dining and Pattaya and Venice? O love why is so much labour lost? Let us not revel in the spirit of poor Orsino and say: "Let music be the food of love". Let us instead, learn to give, care and be happy in the 'other's' world.
