Concepts in Squeak [a dialect and implementation of Smalltalk] have
their origins
in biology rather than in computational math....
That posting is wrong.
Smalltalk's roots are very firmly planted in Lisp,
with perhaps a touch of Logo (which also had its roots in Lisp).
The classic Smalltalk-76 paper even contains a meta-circular
interpreter, which I found reminiscent of the old Lisp one.
The "biological" metaphor in Smalltalk is actually a SOCIAL
metaphor: sending and receiving messages, and a "social"
model of agents with memory exchanging messages naturally
leads to anthropomorphisms.
Also of note, the social metaphor is also very mathematical. It has its
roots in process calculi like the pi-calculus, petri nets, the
join-calculus, etc. The "original" OOP metaphor of Agents is also
strongly aligned to this process calculus interpretation.
(And any anthropologist will defy that sociality has more than a
primitive connexion with biological systems. Animal behaviorists may
disagree.)
