I've read, on several occasions, that emergentism is maybe not all the way contrasted but at least to some degree conflicted with reductionism. As I understand, emergentism is a doctrine within philosophy of mind according to which agglomerations of specimens begin to exhibit properties that are not discerned at the individual level so an emergentist considers them, to some degree, irreducible.
But my question is, why would that be irreducible (if my understanding is correct) and is emergentism really incompatible with reductionism? Why can't those properties be present and (upon some future advancement of science) observable at the individual level where they are latent and only manifest themselves in a certain context, such as when agglomerated in a large crowd. So, if I subscribe to a physicalist doctrine of consciousness, those characteristics are very much encoded in my neural configuration, and detectable as such, they only don't outwardly manifest themselves outside a context in which they can come to prominence. But they very much exist.
I cannot conceive that agglomerations of specimens possess properties not observable on individual level. The idea just kinda creeps me out. It cannot come out of nowhere.
