"Agnosticism and Christianity" in Essays Upon Some Controverted Questions (1892), pp. 350-1, 351-2.
The people who call themselves "Agnostics" have been charged with doing so because they have not the courage to declare themselves "Infidels." It has been insinuated that they have adopted a new name in order to escape the unpleasantness which attaches to their proper denomination. To this wholly erroneous imputation, I have replied by showing that the term "Agnostic" did, as a matter of fact, arise in a manner which negatives it; and my statement has not been, and can not be, refuted. Moreover, speaking for myself, and without impugning the right of any other person to use the term in another sense, I further say that Agnosticism is not properly described as a "negative" creed, nor indeed as a creed of any kind, except in so far as it expresses absolute faith in the validity of a principle, which is as much ethical as intellectual. This principle may be stated in various ways, but they all amount to this: that it is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty. This is what Agnosticism asserts; and, in my opinion, it is all that is essential to Agnosticism. That which Agnostics deny and repudiate, as immoral, is the contrary doctrine, that there are propositions which men ought to believe, without logically satisfactory evidence; and that reprobation ought to attach to the profession of disbelief in such inadequately supported propositions. The justification of the Agnostic principle lies in the success which follows upon its application, whether in the field of natural, or in that of civil, history; and in the fact that, so far as these topics are concerned, no sane man thinks of denying its validity.
The Niomachean Ethics of Aristotle, trans. Robert William Browne (George Bell and Sons: 1889), pp. 252-4.
Now he that sees, perceives that he sees; and he that hears, that he hears; and he that walks, that he walks; and in every other case, in the same manner, there is some faculty which perceives that we are energizing; so that we perceive that we are perceiving, and understand that we are understanding. But this is the same as saying that we perceive or understand that we exist; for existence was defined to be perceiving, or understanding. Now, to perceive that one is alive, is of the number of those things which are pleasant in themselves: for life is a good by nature: and to perceive the good which is inherent in one's self is pleasant. But life is eligible, and particularly to the good, because existence is to them good and pleasant; for by the consciousness of that which is absolutely a good, they are pleased.
Understanding Religious Conviction (University of Notre Dame Press: 1975), p. 118.
There is, however, a form of the fallibility principle which is both significant and acceptable. It holds that even one's most cherished and tenaciously held convictions might be false and are in principle always subject to rejection, reformulation, improvement, or reformation.
Autobiography of Benjamin Franklin (Macmillan: 1909), p. 94
In the conduct of my newspaper I carefully excluded all libeling and personal abuse, which is of late years become so disgraceful to our country. Whenever I was solicited to insert anything of that kind and the writers pleaded, as they generally did, the liberty of the press — and that a newspaper was like a stage-coach, in which any one who would pay had a right to a place — my answer was that I would print the piece separately if desired, and the author might have as many copies as he pleased to distribute himself, but that I would not take upon me to spread his detraction, and that having contracted with my subscribers to furnish them with what might be either useful or entertaining, I could not fill their papers with private altercation, in which they had no concern, without doing them manifest injustice. Now many of our printers make no scruple of gratifying the malice of individuals by false accusations of the fairest characters among ourselves, augmenting animosity even to the producing of duels; and are, moreover, so indiscreet as to print scurrilous reflections on the government of neighboring States, and even on the conduct of our best national allies, which may be attended with the most pernicious consequences. These things I mention as a caution to young printers, and that they may be encouraged not to pollute their presses and disgrace their profession by such infamous practices, but refuse steadily; as they may see by my example that such a course of conduct will not on the whole be injurious to their interests.
"No Stone Will Be Left" in The Way to Love (Random House: 1995), pp. 61-6
Think of a flabby person covered with layers of fat. That is what your mind can become — flabby, covered with layers of fat till it becomes too dull and lazy to think, to observe, to explore, to discover. It loses its alertness, its aliveness, its flexibility and goes to sleep. Look around you and you will see almost everyone with minds like that: dull, asleep, protected by layers of fat, not wanting to be disturbed or questioned into wakefulness. ¶ What are these layers? Every belief that you hold, every conclusion you have reached about persons and things, every habit and every attachment. In your formative years you should have been helped to scrape off these layers and liberate your mind. Instead your society, your culture, which put these layers on your mind in the first place, has educated you to not even notice them, to go to sleep and let other people — the experts: your politicians, your cultural and religious leaders — do your thinking for you. So you are weighed down with the load of unexamined, unquestioned authority and tradition.
"Is Christianity Good for the World?", Christianity Today debate between Douglas Wilson and Christopher Hitchens. (May, 2007)
But it is interesting that the same thing happens to you when you have to give some warrant for trusting in "reason". I noted your citation of LaPlace in your book and am glad you brought him up here. LaPlace believed he was not in need of the God hypothesis, just like you, but you should also know he held this position as a firmbeliever in celestial and terrestrial mechanics. He was a causal determinist, meaning that he believed that every element of the universe in the present was "the effect of its past and the cause of its future."
