"In my concept of time, which is largely connected with evolutionary time, the notion that errors are made by nature, that replication is not perfect, is central. ... We must accept the fact that all the imaginative inventions are to some extent errors with respect to the norm. ... But these errors have the peculiar property of being able to sustain themselves, of being able to reproduce themselves. ... More scientific discoveries are wrong than right. Of course, the wrong ones do not get published so often. But never confuse the process of exposition with the process of discovery. ... The discovery is made with tears and sweat (... with a good deal of bad language) by people who are constantly getting the wrong answer. ... So, of course, more bad science is produced than good and and more bad works of art are produced than good ones. The difference is only that most scientists take care not to exhibit their bad work."
