Examples
“Intelligence, this is a question altogether foreign to any argument from teleology, seeing that teleology, in so far as it is _teleology_, can only rest upon the observed facts of the cosmos; and if these facts admit of being explained by the action of a single causative principle inherent in the cosmos itself, teleology is not free to assume the action of any causative principle of a more ultimate character.”
“By the way, teleology is a word I seldom hear, and this is the first time it's come up in an interview.”
“Perhaps dropping the term teleology helps avoid the confusion witnessed here and it would make it easier to avoid the conflation of terminology used by the ID movement but understanding the history of these arguments is what is important to understand the arguments.”
Francisco Jose Ayala: Darwin's Gift: To Science and Religion - The Panda's Thumb
“If you want to spin that as "we don't know whether teleology is the explanation", I can't really argue with that, but don't pretend that makes teleology "just as likely" as a non-teleological explanation.”
“The moment teleology is discussed, out goes the science – or at least, in comes the contamination with philosophy.”
“What the standard histories of philosophy write about Aristotle's teleology is unfortunately largely wrong, and must be ignored.”
“In other words, how can you explain teleology by dysteleology?”
“To be as clear as possible: teleology is a post hoc inference, not a propter hoc assumption.”
“This means that the inference to teleology is an inference by exclusion.”
“Allen MacNeill: This means that the inference to teleology is an inference by exclusion.”

sionnach Yes, indeed, CSP has much to answer for. And who is due the credit or blame for the puzzling visual? Oct 6, 2012
ruzuzu In the meantime, philosophypagesdotcom says τελος (télos) is the "Greek term for the end, completion, purpose, or goal of any thing or activity. According to Aristotle, this is the final cause which accounts for the existence and nature of a thing. Following Wolff, modern philosophers (often pejoratively) designate as teleological any explanation, theory, or argument that emphasizes purpose." -- http://www.philosophypages.com/dy/t.htm#telg Oct 5, 2012
ruzuzu We should probably blame Charles Sanders Peirce for that Century definition. I'll have to read a little more to figure out what he actually thought of teleology. Oct 5, 2012
