I have just updated my bibliography of works in the English language:
Ludwig Feuerbach: A Bibliography
Aside from the addition of print works, there are now links to YouTube videos.
Here are a few stray quotes gleaned from the Internet, not yet sourced:
"The present age . . . prefers the sign to the thing signified, the copy to the original, fancy to reality, the appearance to the essence . . . for in these days illusion only is sacred, truth profane."
"'Faith moves mountains!' Certainly! Faith does not solve difficult problems; it only pushes them aside."
"The pious one bases faith on human weakness. How weak must be something that is supported by weakness."
And here is a very interesting quote from Feuerbach's Principles of the Philosophy of the Future (1843), Part II: Critique of Hegel, § 21 (different translation):
"The Hegelian philosophy is the last magnificent attempt to restore Christianity, which was lost and wrecked, through philosophy and, indeed, to restore Christianity—as is generally done in the modern era—by identifying it with the negation of Christianity."
Feuerbach constantly highlights the tug of war between philosophy and theology, and which won wins out within the thought of particular philosophers. Here though note also that Feuerbach's remark is applicable to liberal, (partly) demythologized religion.
From a quick scan of Feuerbach's works in English, I've concluded that I first most need to read Lectures on the Essence of Religion (1851).This is a later work than his other noted works on religion and by this time he has revised some earlier views. Also, it seems to be the most general treatment of religion beyond Christianity, with some interesting remarks about philosophers. Lectures I & XXX are available at the Marxists Internet Archive. Both are worth checking out. Lecture I has some interesting commentary on Descartes, Spinoza, and Leibniz, for example. I intend to scan Lecture II, which begins with a treatment of Pierre Bayle. Lecture XXX is "Atheism alone a Positive View."
