Synergy, Synergism, Synergetics

'Synergism' is a traditional Salvation doctrine, according to which Salvation of the individual Soul consists in a combination of personal and divine processes.  It is opposed to doctrines that focus exclusively on one or the other, e. g. that Salvation is earned through deeds, or that it is a unilaterally determined by divine dispensation.  Its origins are in Catholicism, but it can be recognized in Kant's Rationalist concept of the Highest Good.  So, while 'Synergism' can connote an a priori doctrine, 'Synergetics', popularized by Fuller in recent decades, connotes an empirical study of systems in which a multiplicity of influences combine to produce effects that are greater than the sums of their parts.  So, Synergy, per se, has received little systematic Philosophical attention, primarily because the usual locus of study has tended to be Atomist and sedentary, beginning with perceptual processes, e. g. Descartes and Locke.  Accordingly, the concept of 'working together', has typically been conceived as derivative and extrinsic, if conceived at all.
