"The project's advocates imagine that the problem, if they recognise one at all, lies in the variable quality of Wikipedia's individual entries. The solution is obvious: a process in which editors work on the less successful entries and remove the obviously unmerited ones. In reality, the problem is much more fundamental to Wikipedia than that much of its content is a pile of dross. Whereas science and learning pursue truth, Wikipedia prizes consensus. Wikipedia has no means of arbitrating between different claims, other than how many people side with one position rather than another. That ethos is fatal to the advancement of learning. Ideas are refined by being tested; scientific method presupposes scrutiny, experiment and conflict."
