We accepted this hint and carefully investigated the previous psychological history wherever possible. Our trouble was richly rewarded, for we often found, to our surprise, that the disease broke out at a moment of some great emotion which, in its turn, had arisen in a so-called normal way.

Freud’s fundamental investigations into the psychology of hysteria and dreams afforded us the greatest stimulus and help in our work.
A few instances of the latest method in psychiatry will make the subject clearer than mere dry theory. In order to bring home to you the difference in our conception I will first describe the medical history in the older fashion, and subsequently give the solution characteristic of the new departure.
The case to be considered is that of a cook aged 32; she had no hereditary taint, was always industrious and conscientious, and had never been noticeable for eccentric behaviour or the like. Quite recently she became acquainted with a young man whom she wished to marry. From that time on she began to show certain peculiarities.
