[Xmca-l] Shpet & principium cognescenti

[Huw Lloyd]

There seems to be a clear parallel between Vygotsky's use of the
formulation "in itself, for others, for itself" and Shpet's referencing
theological principium cognescenti which according to my brief browsing are
three principles:
principium essendi, principium cognoscendi externum, principium cognoscendi
internum.

Is anyone here familiar with the etymology of these principles and their
bearing on Vygotsky's work?  Is there more than a superficial resemblance?
