The left hand is concerned with the right hemisphere that is intuition, imagination, myth, poetry, religion. The left hand is very much condemned. The society is of those who are right-handed; right-handed means left hemisphere. Ten percent of children are born left-handed but they are forced to be right-handed. Children who are born left-handed are basically irrational, intuitive, non-mathematical, non-Euclidian. They are dangerous to the society; the society forces them in every way to become right-handed. It is not just a question of hands, it is a question of inner politics: the left-handed child functions through the right hemisphere. That, society cannot allow, it is dangerous; he has to be stopped before things go too far.
It is suspected that in the beginning the proportion must have been fifty-fifty: left-handed children fifty percent and right-handed children fifty percent. But the right-handed party has ruled so long that by and by the proportion has fallen to ten percent and ninety percent. Even amongst you here, many will be left-handed but you may not be aware of it. You may be writing with the right hand and do your work with the right hand, but in your childhood you may have been forced to be right-handed. This is a trick, because once you become right-handed your left hemisphere starts functioning. The left hemisphere is reason, the right hemisphere is beyond reason. Its functioning is not mathematical – it functions in flashes, it is intuitive, very graceful, but irrational.
The left-handed minority is the most oppressed minority in the world, even more than the negroes, even more than the poor people. Now if you understand this division you can understand many things. The bourgeoisie and the proletariat: the proletariat is always functioning through the right hemisphere of the brain; poor people are more intuitive. Go to primitive people – they are more intuitive. The poorer the person, the less intellectual. And that may be the cause of his being poor. Because he is less intellectual he cannot compete in the world of reason: he is less articulate as far as language is concerned, reason is concerned, calculation is concerned; he is almost a fool. That may be the cause of his being poor.
And the rich person is functioning through the left hemisphere of the brain: he is more calculative, arithmetical in everything; cunning, clever, logical, planning. That may be the reason why he is rich.
Now the proletariat and the bourgeoisie cannot disappear through communist revolutions, no, because the communist revolution is by the same kind of people. The czar ruled Russia; he ruled it through the left hemisphere of the mind. Then he was replaced by Lenin who is again of the same type. Then Lenin is replaced by Stalin who is even more the same type. The revolution is false because deep down the same type of people are ruling: the ruler and the ruled remain the same; the ruled are of the right-sided hemisphere. So whatsoever you do in the outside world makes no difference really; it is superficial.
The same applies to men and women. Women are right-hemisphere people, men are left-hemisphere people. Men have ruled women for centuries. Now a few women are revolting, but the amazing thing is that these are the same type of women. In fact they are just like men: rational, argumentative, Aristotelian.
