In their fear of death, people try to avoid the thought of it. They try to enjoy life by banishing death from their awareness, by denying death. There is no absolutely perfect human, who from birth is absolutely pure, absolutely without any other form of life, who never experiences physical breakdowns. All human beings have some physical imperfection, large or small, and are living in symbiosis with other organisms, such as bacteria or viruses. Sickness is nothing other than the collapse of that symbiotic balance, a change leading to death.
All humans live in the intermediate zone between total life and total death.
In the future the science of medicine will no doubt head in the direction of learning how to preserve that intermediate state, that state of symbiotic balance with disease organisms. The philosophy of symbiosis is a philosophy of enjoying the symbiosis of life and death. Its Revolutionary Impact of Industry and Society.
