"We are in a world of facts, and we use them; for there is nothing else to use. We do not quarrel with them, but we take them as they are, and avail ourselves of what they can do for us. [...]. I am what I am, or I am nothing. [...]. I cannot avoid being sufficient for myself, for I cannot make myself anything else, and to change me is to destroy me. If I do not use myself, I have no other self to use. My only business is to ascertain what I am, in order to put it to use." (John Henry Newman, An Essay in Aid of a Grammar of Assent)
"Ten thousand difficulties do not make one doubt." (John Henry Newman, Apologia Pro Vita Sua)
