Materia Medica Viva Volume 2 – page 284

Because their character lacks levity and they have a heavy perspective on life, an inability to view life superficially, these patients can easily become depressed after a career disappointment or an emotional upset. They are not, however, overwhelmed by their depression; suicidal depressions are not seen. Their response consists mostly of discontentment and dissatisfaction; they are pleased neither with anything they do nor with what others do for them. They feel as if they are not appreciated enough.
As mentioned, these individuals find their greatest pleasure in their intellectual endeavours, but if they become disappointed, they sometimes become so emotionally affected that they lose interest in these pursuits. Eventually they may go into a state of indifference, apathy, with an aversion to any form of communication with anybody, least of all conversation – aversion to conversation. They become inflexible; it seems as if something is pulling them inward and, at the same time, paralyzing their mobility, their ability to communicate. Just as their muscles and tendons become tensed and constricted, so they feel mentally tense, constricted, and restricted.
A big change now becomes observable in their behavior. Where earlier they were people who took pride in their accomplishments and liked to communicate their ideas, becoming excited when they spoke about them, now they do not want to talk or work; they become indolent, lazy, especially during the morning hours. Mental confusion sets in, and their memory starts to fail; they begin to make mistakes in their writing and speech. And, interestingly, they feel better if they take a walk in the open air by themselves in the morning.
Though I have not yet been able to ascertain it, I feel certain that this remedy possesses even deeper mental pathology.
