In All Talked Out J.D. Trout exemplifies the power of science in the hands of a philosopher, and the result is a timely and urgent argument about the future of philosophy. Based on his 2013 Phi Beta Kappa Romanell Lectures, Trout here presents a novel and positive view of intellectual advancements with respect to traditional topics in philosophy, and explains why these achievements occurred despite the archaic and often retrograde influence of philosophical doctrine and method.

Together, these lines of inquiry lead to a conclusion that while foundational reflection remains as necessary as ever philosophy, as it is conceived in the halls of academia, no longer adds anything distinctively useful. At its best, philosophy is a place to grow new ideas. But many other disciplines can provide such incubation. At the same time, however, Trout argues that we don't have to kill philosophy; we just have to figure out what is worth preserving from it.

Following a spirited introduction, the first lecture takes stock of the growing field of evidence-based approaches to reasoning, and in light of these scientific developments, criticizes important failures in epistemology as it is currently practiced in the English speaking world. The second lecture examines the psychological impulse to explain, the resulting sense of understanding, and the natural limits of cognitively appreciating the subject we have explained. The final lecture presents the proper reaction to the idea that scientific evidence matters to responsible governance.
