We live in world of great complexity; we live in the crystalline world and the biological world and we live in a a world of technical and technological order and clarity, and a world of personal and social disorder and confusion.
In the crystalline world atoms combine in ways determined by atomic structure that never varies. Whereas in the biological world, especially after this world has taken on a conscious component, we can begin to speak about creation in that this biological world is reflexive. It is a world with multiple feedback loops wherein the outputs affect the inputs and this is often determined by complex and constantly variable interactions.
A person can walk the corridors of any big city hospital and observe the effectiveness of human rationality in action. One can also visit the UN building in NYC or read the morning papers and observe just how ineffective, frustrating and disappointing human rationality can be. Why does human reason perform so well in some matters and so poorly in others?
We live in two very different worlds; a world of technical and technological order and clarity, and a world of personal and social disorder and confusion. We are increasingly able to solve problems in one domain and increasingly endangered by our inability to solve problems in the other.
Normal science, as defined by Thomas Kuhn in The Structure of Scientific Revolutions, is successful primarily because it is a domain of knowledge controlled by paradigms. The paradigm defines the standards, principles and methods of the discipline. It is not apparent to the laity but science moves forward in small incremental steps. Science seldom seeks and almost never produces major novelties.
Science solves puzzles. The logic of the paradigm insulates the professional group from problems that are unsolvable by that paradigm. One reason that science progresses so rapidly and with such assurance is because the logic of that paradigm allows the practitioners to work on problems that only their lack of ingenuity will keep them from solving.
Science uses instrumental rationality to solve puzzles. Instrumental rationality is a systematic process for reflecting upon the best action to take to reach an established end. The obvious question becomes `what mode of rationality is available for determining ends?’ Instrumental rationality appears to be of little use in determining such matters as “good” and “right” (at least as has been defined in the discussion of ethics for centuries).
There is a striking difference between the logic of technical problems and that of dialectical problems. The principles, methods and standards for dealing with technical problems and problems of “real life” are as different as night and day. Real life problems cannot be solved only using deductive and inductive reasoning.
Dialectical reasoning methods require the ability to slip quickly between contradictory lines of reasoning. One needs skill to develop a synthesis of one point of view with another. Where technical matters are generally confined to only one well understood frame of reference; real life problems become multi-dimensional totalities.
When we think dialectically we are guided by principles not by procedures. Real life problems span multiple categories and academic disciplines. We need point-counter-point argumentation; we need emancipatory reasoning to resolve dialectical problems. In other words, need critical thinking skills and attitudes to resolve real life problems.
It seems as though many in our society are not sophisticated enough to make the kind of decisions that are required to prevent the destruction of our civilization. It seems to me that we must put a much greater emphasis upon this weakness. I think that the foundation for such an increase in intellectual sophistication requires that, at a minimum, a much greater proportion of our citizens must develop a comprehension of the fundamentals of critical thinking.
