What's the difference between mechanism and mechanist?
Mechanism
Definition:
(n.) The arrangement or relation of the parts of a machine; the parts of a machine, taken collectively; the arrangement or relation of the parts of anything as adapted to produce an effect; as, the mechanism of a watch; the mechanism of a sewing machine; the mechanism of a seed pod.
(n.) Mechanical operation or action.
(n.) An ideal machine; a combination of movable bodies constituting a machine, but considered only with regard to relative movements.

Mechanist
Definition:
(n.) A maker of machines; one skilled in mechanics.
(n.) One who regards the phenomena of nature as the effects of forces merely mechanical.
Example Sentences:

(7) Unfortunately, current risk assessment practices make very little use of the kind of detailed mechanistic information that molecular epidemiology can provide.
(8) aggregation, adhesion to endothelium, directed migration and phagocytosis) are mechanistically related and mediated by a set of molecules which belong to a larger group of adhesion molecules (Integrins) mediating similar phenomena critical for immune surveillance, lymphocyte homing, morphogenesis and thrombogenesis.
