[Undated]

The man who is mentally healthy is able to gain strength and consolation and the material through which he can achieve mental development through his contact with reality, no matter whether that reality is painful or not. This view may owe its origins to experience in no way metaphysical, but such as might be achieved through failure to admit the existence of a physical hazard to physical progress and the resultant fall. The reciprocal view is that no man can become mentally healthy save by a process of constant search for fact and a determination to eschew any elements, seductive or pleasurable, that interpose themselves between himself and his environment as it really is. Like the earth, he carries with him an atmosphere, albeit a mental one, which shields him from the mental counterpart of the cosmic and other rays at present supposed to be rendered innocuous to men, thanks to the physical atmosphere.
