"The second advantage claimed for naturalism is that it is equivalent to rationality, because it assumes a model of reality in which all events are in principle accessible to scientific investigation"
About this Quote
The key maneuver is in “equivalent to rationality.” Johnson is pointing at a rhetorical conflation: if you define “rational” as “scientifically investigable,” then anyone who questions naturalism can be dismissed as irrational by definition. It’s a critique of boundary-setting, not of science per se. He’s interested in the way a metaphysical assumption (that reality is fully continuous with scientific explanation) can masquerade as an uncontroversial commitment to reason.
His wording also slips in a pressure point: “in principle accessible.” That clause is doing heavy lifting. It acknowledges that science may not currently explain everything, but insists that everything is explainable within the scientific frame. Johnson’s subtext is that this is faith in a program, not a conclusion from evidence, and that it quietly forecloses other kinds of explanation before they’re even heard.
Contextually, Johnson’s work is tied to debates over evolution, intelligent design, and the cultural authority of science in education. The quote isn’t just philosophy; it’s institutional politics: who gets to define reality in the classroom, and what counts as a permissible question.
