Preface to the Third Edition.

The principles I have followed in this new edition of Kant’s Philosophical Doctrine of Religion Original: "Philosophische Religionslehre," referring to Kant's 1793 work Religion within the Boundaries of Mere Reason are the same as those that guided me in my editions of the Critique of Pure Reason (O. Hendel, 1899) and the Critique of Judgment (Dürr, 1902). I may refer the reader to the more detailed prefaces found there.

The Introduction has undergone an expansion in that the sections on the origin, content, fundamental tendency, reception, and subsequent influence of the writing are now preceded by a coherent presentation of Kant’s religious development. The penultimate (V.) section of the Introduction consists this time of textual-philological remarks Technical notes regarding the history and physical state of the manuscript and printed versions restricted to the briefest possible scope. Finally, as "Appendices," there follow three pieces never before printed in any edition of Kant, published for the first time by W. Dilthey in the Archive for the History of Philosophy (1890) Vol. III, Issue 3, p. 429 ff.: 1) The draft of Kant’s letter to a theological faculty concerning the freedom to print his work This refers to Kant's struggles with Prussian censorship under King Friedrich Wilhelm II, 2) and 3) two previously unprinted drafts for the preface of our current work. — In addition to the index of persons and subjects (terminological dictionary), a list of the biblical passages cited or interpreted by Kant has been added.

The text was based on the second original edition (from 1794), but all deviations from the first (insofar as they did not concern orthography or punctuation) have been noted, as well as the variants of the other editions; our own textual changes are presented in a special list (for further details, see Section V of the Introduction).
