Content:  Truth and Tolerance (Glaube – Wahrheit – Toleranz: Das Christentum und die Weltreligionen) is a book written by Joseph Cardinal Ratzinger (Pope Benedict XVI). The book discusses faith, religion, culture, freedom, and truth, with special emphasis on the Christian religion and how it relates to these and if it can continue to make an absolute claim as the true religion. In the preface, he states that "beyond all particular questions, the real problem lies in the question about truth." He first tries to understand what culture is and how cultures relate to one another. Then he tries to understand man, what he is and how he can become himself. Then, in the end, he deals with the question of whether man is made for the truth and in what way he can put the question of truth.

Title: Brian Leiter
Content:  Leiter's book, Why Tolerate Religion?, published by Princeton University Press, has proved controversial. The political philosopher John Gray wrote, "A model of clarity and rigour and at points strikingly original, this is a book that anyone who thinks seriously about religion, ethics and politics will benefit from reading." Christopher L. Eisgruber, the President of Princeton University, said. "Every reader will learn something from this remarkable book, and, beginning now, every serious scholar of religious toleration will have to contend with Leiter's bold claims." By contrast, the website of the conservative Family Research Council said the book was "one of the most troubling and intellectually discreditable books by a serious American scholar in some time." The book was named an "Outstanding Academic Title" by Choice in 2013. Leiter has also published work on meta-ethics, social epistemology, the law of evidence, and on philosophers Karl Marx, Martin Heidegger, and Ronald Dworkin.

Title: A Critique of Pure Tolerance
Content:  He accused Marcuse of having "taken over from liberal and right-wing critics of the European revolutionary tradition a theory which they falsely ascribed to the left, but which was rarely held until Marcuse espoused it." Against Marcuse, he argued that the proper end of tolerance is not truth but rationality, and that Marcuse's proposals undermined the possibility of rationality and critical discussion. He stated that Marcuse's case against tolerance made those radicals who espouse it "allies of the very forces which they claim to attack." The political scientist Ronald Bayer identified Marcuse's arguments about "repressive tolerance" as an influence on gay rights activists, who disrupted lectures by psychiatrists and refused to tolerate the views of their opponents as they campaigned for homosexuality to be declassified as a mental disorder.
