I don’t mind a theist being inspired by another person’s arguments or ideas. I don’t mind a theist referencing someone else’s ideas and arguments in his own arguments. There’s nothing wrong with including a link or a quoted passage, in a correspondence, to someone else’s data or views. But if a person comes to me announcing that he wants to talk to me about his beliefs, he should at least do me the courtesy of presenting his beliefs—whether or not they are supplemented by the ideas of those who have influenced his thinking.
The author of Article X, from which the theist quotes, is not the person who contacted me to discuss her beliefs. If that author wants to hear my views about her beliefs, she is able to write to me and request my feedback. But I see no value in pretending that a long strand of copied and pasted material from her article is the view of the theist who wrote to me to dialogue about his beliefs.
If a theist writes and wants to know my response to a particular article or view that is not his own, that’s fine. But he should refrain from calling it his belief, if all he can do is parrot the argument of someone else. If he lacks sufficient understanding of the concept to be able to so much as restate it in his own terms or respond to questions without running back to the source, then he shouldn’t put it forward as his belief.
Forming our own beliefs in life is not the same as memorizing and internalizing someone else’s arguments and ideas. To label such things as our own beliefs is plagiaristic and shows a woeful lack of understanding about what constitutes forming beliefs of our own. In order to dialogue about what I believe requires I have a firm enough grasp on the belief to express it clearly, in my own terms, to others, and also to respond to questions without seeking input from any source beyond my own mind. Anything that can honestly be labeled as my belief can exist nowhere but inside my own mind. A prerequisite to holding a belief is understanding the belief. It is not possible for a person to both assert a proposition is true, and to fail to understand the proposition. When questioned about what we believe—why should we need to go and look it up? If I find myself looking up my response to a question that concerns what I claim I believe, clearly, I have a dilemma.
If someone were to ask me, for example, what I believe regarding UFO activity on our planet, I can’t imagine it would make sense to that person if I said, “give me a second to go and look up what Carl Sagan has to say about that, because I believe whatever he says.” How can I call it my belief if it (a) is not contained within my own mind, and (b) I don’t even know what it is I’m claiming I believe while I am asserting I accept it as true?
I seem to see more often than is comfortable long-winded e-mails that ultimately say, “I don’t understand it myself, but I absolutely believe it.”
