What do you mean by ‘theory’?

Theories can be unconscious states of mind as well as conscious ones, inexplicit ones as well as explicit ones, false ones as well as true ones, and conflicting ones as well as consistent ones.

‘Enacting a theory’

Anyone who is interested in learning those subjects learns what ‘expressed’ and ‘executed’ mean without conscious effort. No sweating over the nuances of a definition is ever involved. What one does is start with any commonsense, flawed conception of ‘expressed’ or ‘executed’, and then one refines that conception in parallel with learning the theory.

Taking Children Seriously and fallibilism

We believe that it possible for human beings, through conjecture, reason and criticism, to come to know and understand truths about the world, including truths about the human condition and about specific people, and including truths about matters that are not experimentally testable. We do not believe that we possess the final truth about any of these matters, but we do believe that our successive theories can become objectively truer—with more true implications and fewer errors.

A discussion about whether problems are solvable

Those who believe the conflict-of-interest theory alleging that problems are not soluble will always be puzzled when they find a situation that looks like an inherent conflict of interest but turns out not to be, as commonly happens when people start taking their children seriously.

Clarifying Karl Popper’s epistemology

Karl Popper’s theory prevails because it solves problems other theories of the growth of knowledge fail to solve, it is a better explanation than its rivals, and it unifies ideas previously thought to be unconnected.

Educational theory: science or philosophy?

One of our best theories (the framework theory of evolution) is not scientific, but that it is none the worse for that. And all scientific theories rely on a philosophical framework.

Trying to turn philosophy into science is a mistake

We are always dealing with our theories of what is happening, never something more ‘pure’. ‘Observed behaviour’ is shorthand for ‘our theories of observed behaviour’. All observation is theory-laden. Sometimes theories’ apparent failures in empirical tests are no such thing—we just made a mistake. Science does not have any special status.

Philosophical theories are refuted by argument, not empirical tests

There is no point demanding testability of an educational theory. What one can do with philosophical theories, is refute them by argument. Empirical testing is just one of a number of types of intersubjective criticism, and the vast majority of all criticism is by argument, even in science. Most scientific theories are refuted before they even get to the stage of empirical testing.
