Excellent - and I did not know you are a real Jungian (it would seem to me now...on this plane of being my me, that is), and yes: I realize you've got to sing with the band but - even so - as to:
I have encountered countless somatic complaints with psychological roots.
I'd say: psychological roots are (in biomedical and physical fact) rooted in - experienced manifestations of - somatic roots (so to speak).
Occam's razor (or Ockham's razor), is the meta-theoretical principle that "entities must not be multiplied beyond necessity" (entia non sunt multiplicanda praeter necessitatem) and the conclusion thereof, that the simplest solution is usually the correct one.
And then one has, by a process of mere (male? ) analytical logic:
"encountered countless somatic complaints with somatic roots (personal experiences)"
and then we agree wholly, while also applying frater Ockham's Razor...
Chapeau, partial colleague of this psychologician: A sane Jungian! There be real miracles next, methinks, as if that were possible !
The principle is attributed to 14th-century English logician, theologian and Franciscan friar, William of Ockham. Occam's razor may be alternatively phrased as pluralitas non est ponenda sine necessitate ("plurality should not be posited without necessity"). The principle is often expressed in Latin as the lex parsimoniae (translating to the law of parsimony, law of economy or law of succinctness). When competing hypotheses are equal in other respects, the principle recommends selection of the hypothesis that introduces the fewest assumptions and postulates the fewest entities while still sufficiently answering the question. It is in this sense that Occam's razor is usually understood. To quote Isaac Newton, "We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances. Therefore, to the same natural effects we must, so far as possible, assign the same causes."
