Doubt Quotes - page 46
The innovator, however, must in the first place be discontented, he must doubt the value of what he is doing or question the accepted ways of doing it. And secondly, he must be prepared to take fresh paths, to venture into fields where he is by no means expert. This is true, at least, of major forms of innovation; they make it possible for other men to be expert, but are not themselves forms of expertise. Freud was not an expert psycho-analyst; before Freud wrote there was no such thing; he created the standards by which psycho-analysts are judged expert. Neither was Marx an expert in interpreting history in economic terms nor Darwin an expert in evolutionary biology. If a man is trained, purely and simply, to be expert and contented in a particular task he will not innovate; Freud would have remained an anatomist, Marx a philosopher, Darwin a field-naturalist.
John Passmore
But since the Modernists (as they are commonly and rightly called) employ a very clever artifice, namely, to present their doctrines without order and systematic arrangement into one whole, scattered and disjointed one from another, so as to appear to be in doubt and uncertainty, while they are in reality firm and steadfast, it will be of advantage, Venerable Brethren, to bring their teachings together here into one group, and to point out the connexion between them, and thus to pass to an examination of the sources of the errors, and to prescribe remedies for averting the evil.
Pope Pius X
