Reply #44: Of course they do, but not absolutely so, i.e. if they were absolutely unique

we could not survive as a species.

There are differences and similarities that vary over time and situations. If it were possible to construct valid reliable instruments to quantify the differences and similarities for a given individual and their learning experiences over time, we'd probably see proportions of similarity to difference that I propose we roughly characterize as somethings like 50:50, 20:80, 90:10 ... depending upon the individual.

And, for whatever a given person's quite possibly strongly unique learning characteristic(s) might or might not be, unless that person is capable of existing entirely on their own, their relationships to their group will require that they LEARN/adapt in ways that serve the functionality of those relationships within a group. No one is saying that individuals have to become totally subsumed in a group, just that individuality can be and is served in group contexts and teachers have responsibility to BOTH the individual and the group.
