In this paper, it is argued that theoretical physics is more akin to an organism than to a rigid structure. It is in this sense that the epithet, “sick”, applies to it. It is argued that classical physics is a model of a healthy science, and the degree of sickness of modern physics is measured accordingly. The malady is located in the relationship between mathematics and physical meaning in physical theory.
