Does "men are so constituted" mean "men are born in such structure"?

Context:

W.R. Houston may have been the first to have spoken of a doctor's deliberate application of harmful "placebo" procedures, as distinct from the other, harmless sort of "placebo" procedures a doctor might apply and whose "usefulness was in direct proportion to the faith that the doctor had and the faith that he was able to inspire in his patients." Houston (1938, p. 1418) wrote:

... [and while the http://en.wikipedia.org/wiki/Efficacy of the placebo procedure] is believed in by the doctor, [the placebo procedure itself] is no longer harmless but harmful, sometimes very dangerous. It would seem peculiarly contradictory to speak of the painful and dangerous placebo, yet men are so constituted that they feel the need in dire extremity of resorting to dread measures. Nervous patients in particular, feel that a certain standing and sanction is bestowed upon their maladies when violent therapeutic measures are used.
