Philosophy is a disease, and it is like a cancer: no medicine exists for it yet, you have to go through surgery, a great operation is needed. And philosophy has a similar type of growth, a canceric growth: once it is in you it goes on growing by itself, and it takes all your energies. It is a parasite. You go on becoming weaker and weaker and it becomes stronger and stronger and stronger. Every word creates another word — and it can go on infinitely.
