Psora. Compton Burnett

……….It is due, let us say, to psora, but we have no clear conception of What psora is.

Psora needs to  be split up into its component parts, no easy task; it roots in the vague, its trunk and boughs run  away into anywhere.

The Psora of the homoeopaths seems somehow true, but it has no proper  beginning, no definite course, and ends in pathological chaos. Perhaps we study it in Hahnemann, and in the best writers on the subject, and after doing our best to master it, we rise  from our studies with no clear idea, and we finally decide to abandon psora as an intangible  myth, and then we proceed with our clinical work; but, before long, we stumble against a very  tangible something, and on looking at the stumbling block, we find writ large upon it the word  Psora! Have I then hit upon a solution of the psora-problem? No; but if we cannot break the
whole faggot, we may perchance break one stick of it.
