Yesterday someone told me about an English philosopher Thomas Hobbes. As I was reading a bit about him, I came across a very different perspective on morals. It mentioned morals are derived from self-interest !
Here's a question: Is rape a right or wrong ?
The obvious answer is wrong. Rape is an act involving two or more people. And this act takes place without the consent of one of the individuals.
Now, another question is asked. Why is consent of an individual important ? And this is where the trouble begins. Consider a hypothetical society in which every individual is allowed to do anything. There is no right and there is no wrong. In such a society the strongest person will be allowed to do anything he desires and the weak won't have a choice. So, the strongest man can rape any woman he wants and get away with it as there is no right or wrong in this case. But, majority of the society is weak. The weaker section will not want their closed ones to be raped. Hence, as this society evolves a moral is introduced that rape is wrong. This moral is thus derived from self-interest.
To understand how a society evolves, we need to understand a term called evolutionarily stable state (ESS). Most of you must have watched the movie 'Shark Tales'. In that movie we see a bunch of fish cleaning the teeth of whales. This happens in real world as well. The whale is a stronger fish of the lot and cleaners(I just came up with the term) are the weak.
Now lets consider four possibilities which might occur:
1. The cleaner fish and the whales never met.
2. The cleaner fish take advantage of opportunity and eat the flesh of the whales and get away with it.
3. The whales let the cleaners clean their teeth and after that eat it.
4. Both engage in a symbiotic relationship. The cleaners clean the teeth and whale lets them go.
Now, over a period of time the first possibility will get eliminated. For the second possibility, as the time goes on, the future generations of whales will become intelligent and will not allow the cleaners to come near them. Similar will be the case in the third possibility. Now, the fourth option is what we see happening now. So, this possibility now becomes an Evolutionarily Stable State.
The same concept explains the evolution of the society. Now. lets go back to the society where anyone can do anything and there is no right or no wrong.
Here's an excerpt from Leviathan (book by Thomas Hobbes):
In such condition, there is no place for industry; because the fruit thereof is uncertain: and consequently no culture of the earth; no navigation, nor use of the commodities that may be imported by sea; no commodious building; no instruments of moving, and removing, such things as require much force; no knowledge of the face of the earth; no account of time; no arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.
And thus moral, ethics and laws are formed and we now live in a society which is an Evolutionarily Stable State.
