Principles of constructivism are used here to explore how organisms develop
tools, subagents, scaffolds, signs, and adaptations. Here I discuss reasons why
organisms have composite nature and include diverse subagents that interact in
partially cooperating and partially conflicting ways. Such modularity is
necessary for efficient and robust functionality, including mutual construction
and adaptability at various time scales. Subagents interact via material and
semiotic relations, some of which force or prescribe actions of partners. Other
interactions, which I call "guiding", do not have immediate effects and do not
disrupt the evolution and learning capacity of partner agents. However, they
modify the extent of learning and evolutionary possibilities of partners via
establishment of scaffolds and constraints. As a result, subagents construct
reciprocal scaffolding for each other to rebalance their communal evolution and
learning. As an example, I discuss guiding interactions between the body and mind
of animals, where the pain system adjusts mind-based learning to the physical and
physiological constraints of the body. Reciprocal effects of mind and behaviors
on the development and evolution of the body includes the effects of Lamarck and
Baldwin.
