Beauty lies in the eyes of the beholder. But what attracts me more is the beauty that cones from within, the inner beauty, the purity of heart and soul. Cause no one is responsible for his or her superficial beauty but one's inner beauty is self cultivated and nurtured. Yes brain and beauty would be good but they do not stand of without an inner purity.
Also I am sure you have heard the oft repeated joke of beauty and brains attributed to playwright and critic George Bernard Shaw.
Now coming back to the cruel nature of the brain, it is due to the very nature of creation-duality- light and darkness, rain and shine, male and female, love and hatred. To prevent recurrence of such atrocities, we humans have collectively bound ourselves under several laws, regulations, treaties.Those are remedies coming from the same source. When the brain goes wrong it can correct itself whereas beauty turning to ugliness cannot on its own become beautiful again.
Brain can produce beauty through a cosmetic surgery, for an example.But how can beauty ever produce a brain?
Just imagine a scene - you meet a mentally retarded child struggling to eat, drink, dress or urinate- some basic necessities of life. What will be your prayer for that child then? To give that child beauty or brain?
Thus by ethos, pathos, nomos and logos brain appears superior and preferable to beauty. But we are all humans. There is nothing wrong if we covertly or overtly desire to get the brain of an Einstein and the beauty of a Cleopatra.
I conclude my cent worth of opinion.Thank you all for reading it.
