Constructivism

Constructivism

The term constructivism denotes a heterogeneous set of theoretical approaches currently stemming from areas so diverse as biology, neurophysiology, philosophy, sociology, cybernetics, cognitive psychology, rhetoric, and literary studies. In all their variety they share the basic idea that knowledge cannot be based on some kind of correspondence to or representation of actual reality but only on the active cognitive constructions or cognitive operations of an observer. Any possible "objects" of experience and knowledge are embedded in cognitive and social processes.

Historically speaking the roots of constructivism begin in ancient skeptical philosophy, pass through the enlightenment philosophy of Immanuel Kant (1724–1804), the philosophy of language, and eventually to pragmatism. The most recent versions are radical constructivism and operational constructivism, where the term construction refers (1) to the construction of reality, (2) the construction of knowledge, and (3) the construction of tools and skills for human cognition.

Important impulses for radical constructivism were provided by Heinz von Foerster (1911–) due to his insights into the epistemological implications of the unspecified coding of external stimuli in the brain. The world as human beings know it, by means of their sense organs, is the product of internal mental activity. In this respect modern versions of constructivism draw on the concept of autopoiesis as it was introduced by the theoretical biologist Humberto Maturana (1928–) into epistemological discourse. According to the principle of autopoiesis every cognitive system operates on the basis of operative closure, that is to say, without direct input from its environment. Any stimulus from the environment can only stimulate the system to recursively produce its own elements and react to its own inner states. Hence any kind of knowledge or insight is an internal construction. However, this neither leads to relativism nor to the denial of an external reality. Constructivism should not be conflated with strong forms of idealism or antirealism. Yet any correspondence or mirror-theory of knowledge and truth is rejected because nothing corresponds to the internal categories, structures, and elements. Instead, categories of "compatibility," "fitting," or "viability" are of ultimate importance for constructivism since the external reality discriminates among the human constructions in favor of acceptable and fitting knowledge, assumptions, and cognitive skills. In addition, the self-referential and recursive operations inside the cognitive system produce stable states that tend to be taken as "givens" and can furthermore be socially stabilized in a broader culture.

In Niklas Luhmann's (1927–1998) operative constructivism, any production of explicit knowledge is "second-order-observation" since it is not data but other observations that are observed. This second order observation can see the distinction between the analyzed observation and its contingent and constructed character, yet without simultaneously being able to see the contingency of its own observation. What is observed are contingent constructions, but the "own" observation is—due to the blind spot within every observation—assumed to be "realistic." In modern society, where every social subsystem observes "the world" in its own way, this hybrid combination of constructivism and realism leads to a polycontextual ontology.

Due to the strong and widely held realistic assumptions within science and theology, constructivism so far has not attracted very much attention in the dialogue between religion and science. Constructivism does however argue for a nonfoundationalist view of knowledge that opens up new avenues for this dialogue. Moreover, based on the idea of autopoiesis in cognitive systems and its pragmatic orientation, constructivism vividly rejects any notion of reductionism between various cognitive approaches that seek to cope with "reality." Instead it emphasizes the limitedness and fragmentary nature of all human knowing. In addition, constructivism highlights the intimate bond between knowledge and ethics. Unexplored is the contribution of more socially oriented forms of constructivism in answering the question of the way in which, for example, the Christian faith exercises a subtle yet crucial influence on the nonreligious constructions of the wider culture. However, in order to fully embrace constructivism as religious epistemology, theology would have to accept the objectionable claim of God being a human construction for coping with life. And yet constructivism reflects at least one aspect of a central religious insight: Religious knowledge cannot secure its own stability, adequacy, and truth unless God makes Godself present in human understanding and knowing—a process often called revelation.
