"As Hegel wrote: `This is what constitutes the character of mechanism, namely, that whatever relation obtains between the things combined, this relation is extraneous to them that does not concern their nature at all, and even if it is accompained by a semblane of unity it remains nothing more than composition, mexture, aggregation, and the like.´2
Thus, in this conception wholes possess an intextricable unity in which there is strict reciprocal determination between parts. This vision of organismic theory is much harder to eliminate because it is not just a matter of rejecting an old won-out image and because its impact on sociology goes beyond functionalism.
It is clear that assemblage theory, in which assemblages can be component parts of other assemblages (leading to internal organization behind nonlinear and catalytic causality), and in which assemblages are always the product of recurrent processes yielding populations (involving statistical causality), can accommodate these complex forms of causal productivity."
