Rationality in Science, Religion, and Everyday Life.. A Critical Evaluation of Four Models of Rationality

This monograph presents a systematic examination of four influential models of rationality and their implications for understanding the relationship between scientific, religious, and everyday reasoning. Stenmark analyzes the formal-logical model, the contextual model, the social practice model, and the evolutionary model, evaluating each framework's capacity to account for rational belief formation across different domains of human inquiry.

The formal-logical model, which privileges deductive validity and empirical verification, emerges as inadequate for capturing the full spectrum of rational practices. Stenmark demonstrates that this narrow conception fails to accommodate much of scientific theorizing, let alone religious or quotidian reasoning. The contextual model, advocated by philosophers like MacIntyre and Toulmin, proves more promising by acknowledging that rationality operates relative to specific intellectual traditions and their internal standards. However, Stenmark identifies limitations in its ability to adjudicate between competing traditions or explain rational belief revision.

The social practice model, drawing on sociology of knowledge, locates rationality within communal activities and shared norms. While this approach illuminates the social dimensions of belief formation, Stenmark argues it risks collapsing into relativism and cannot adequately distinguish between rational and irrational social practices. The evolutionary model, which grounds rationality in adaptive cognitive mechanisms, offers naturalistic explanations for belief-forming tendencies but struggles to establish normative standards for distinguishing truth-conducive from merely survival-enhancing beliefs.

Stenmark's analysis reveals that each model captures important aspects of rationality while exhibiting significant blind spots. His work contributes to the God debate by challenging simplistic dichotomies between scientific and religious reasoning. Rather than privileging one domain over another, he demonstrates that rationality itself resists reduction to any single model. This has profound implications for evaluating religious beliefs: if scientific rationality cannot be captured by formal logic alone, then religious rationality need not be measured solely by empirical standards.

The monograph's significance lies in its meticulous philosophical analysis showing that disputes about the rationality of religious belief often rest on contested conceptions of rationality itself. By exposing the limitations of reductionist approaches, Stenmark creates space for more nuanced discussions about the epistemic status of religious claims. His work suggests that defending or critiquing religious belief requires first clarifying which model of rationality one employs, as this choice significantly shapes the evaluation's outcome.
