Philosophers of Consciousness is both an expository study of the thought of the six figures it focuses on and an original exploration of the themes they address. In addition, as Eugene Webb states, "it does not hesitate to probe the more problematic areas of the thought of each thinker and to suggest what to some of their advocates will probably seem rather bold and controversial interpreations of their ideas."

The book reveals some deep differences that set the six off against one another in what is basically a clash between the intellectual emphasis of Lonergan and the more existential approaches of the other thinkers in this study. Readers of Kierkegaard may find much of Webb's interpretation surprising and perhaps disturbing.
