Now, although hypertension is accentuated by modern civilisation, it is not specifically a disease of civilisation. It is a disease of consciousness--that is, of being human. The farm labourer going to work is as likely to ignore his surroundings as the harassed car salesman. And if the inhabitants of some Amazon village are 'closer to nature' than New Yorkers, this is usually at the cost of dirt and ignorance and inconvenience. Hypertension is the price we pay for the symphonies of Beethoven, the novels of Balzac, the advances in medical knowledge that prevent children dying of smallpox. However, it is not a necessary and inescapable price. It is the result of ignorance, of bad management of our vital economy. The point to observe here is that although hypertension may not be necessary, it is as widespread as the common cold. It would not be inaccurate to say that all human beings live in a state of 'vigilance' and anxiety that is far above the level they actually need for vital efficiency. It is a general tendency of consciousness to 'spread the attention too thinly'; and, like an over-excited child with too many toys on Christmas Day, the result is nervous exhaustion.
