Illness is used as a part of man’s motivation. What I mean is that there is no human motivation that may not at some time be involved with illness, for often it is a means to a desired end–a method of achieving something a person thinks may not be achievable otherwise.
One man might use it to achieve success. One might use it to achieve failure. A person might use it as a means of showing pride or humility, of looking for attention or escaping it. Illness is often another mode of expression, but nowhere does science mention that illness might have its purpose, or its groups of purposes, and I do not mean that the purposes themselves are necessarily derogatory. Illness are often misguided attempts to attain something the person thinks important.
Sickness can be a badge of honor or dishonor—but there can be no question, when you look at the human picture, that to a certain extent, but an important one, suffering not only has its purposes and uses, but is actively sought for one reason or another.
