Smolin and a number of other critics of string theory have quite vigorously argued that the string physicists’ trust in the viability of their theory is unfounded and constitutes an unfortunate deviation from the path of legitimate scientific reasoning. I think that those critics make two mistakes. First, they implicitly presume that there is an unchanging conception of theory confirmation that can serve as an eternal criterion for sound scientific reasoning. If this were the case, showing that a certain group violates that criterion would per se refute that group’s line of reasoning. But we have no god-given principles of theory confirmation. The principles we have are themselves a product of the scientific process.
