Fullerton opens his introduction by defining philosophy not as a body of doctrines but as a distinctive mode of reflective thinking, one that scrutinizes the assumptions underlying everyday experience and scientific inquiry. He immediately distinguishes this from the “plain man’s” unexamined belief in material things, setting up a recurring tension between naive realism and philosophical reflection. The book is organized around six explicit aims, from clarifying what philosophy covers in contemporary universities to offering practical advice on spirit and method. This structured, almost syllabic approach gives the work a pedagogical clarity rare in philosophical introductions.

The Architecture of Inquiry

Fullerton’s book is built on a clear, almost architectural plan. The preface lists six specific undertakings, and the chapters follow them in order. The first two chapters define philosophy and reflective thought; the next nine present a doctrine (the author’s own “System of Metaphysics” in outline); and the final chapters survey historical schools. This division is not arbitrary: Fullerton insists that one cannot treat philosophical problems without taking a standpoint, yet he aims to present that standpoint as an example rather than a dogma. The result is a text that moves from definition to problem to historical context, each section cross-referenced to his larger work. The reader is never left to wonder where the argument is heading.

Recurring Images: Automata, Purpose, and Divine Order

Throughout the excerpts, Fullerton returns to a cluster of images that anchor his argument. He dismisses the notion of humans as “physical automata with parallel psychical states” as an abuse of language, insisting that minds are active and that purpose is the mark of agency. This image of the automaton recurs as a foil for his teleological view. Later, he links orderliness to the idea of Divine Providence, suggesting that the same world that seems mechanical can be seen as purposive if we adopt a theistic perspective. These images—automaton, purpose, divine order—are not decorative; they structure his defense of free will and moral responsibility against mechanistic reductionism.

Movement Between Common Sense and Reflection

Fullerton repeatedly stages a movement from the “plain man’s” view to philosophical reflection. In Chapter II, he notes that the plain man believes he directly perceives material things; reflection calls this into question. Later, he returns to this pattern when discussing representative perception, showing how early thinkers began to doubt what seemed obvious. This back-and-forth is not merely expository: it enacts the very process of philosophical thinking that Fullerton defines. The reader is invited to see how common sense gives way to problems, and how those problems lead to doctrines. The movement is dialectical but not confrontational; Fullerton’s tone remains that of a guide leading a student step by step.

The Role of Historical Background

In the final chapters, Fullerton turns to the historical background of philosophical types, arguing that “to understand the present, one must know something of the past.” He begins with representative perception, tracing how the problem of knowledge emerged early in speculative thought. This historical turn is not a mere appendix; it is integral to his method. By showing how doctrines arose from reflection on earlier problems, he reinforces his central claim that philosophy is a reflective activity with a history. The reader is left with a sense that philosophical problems are not timeless puzzles but evolving questions shaped by the thinkers who grappled with them.

Fullerton’s introduction is best read as a guided tour rather than a reference work. The reader should pay attention to the way he moves between common sense and reflection, and to the recurring images that tie his argument together. The historical chapters are not optional; they show how the problems of earlier chapters were actually confronted. For those new to philosophy, the practical admonitions in the final pages are worth noting: Fullerton wrote them, he says, from personal experience of confusion. They may spare the reader some of that same anxiety.
