The genuine inquirer wants to get to the truth of the matter that concerns him, whether or not that truth comports with what he believed at the outset of his investigation, and whether or not his acknowledgement of that truth is likely to get him tenure, or to make him rich, famous, or popular. So he is motivated to seek out and assess the worth of evidence and arguments thoroughly and impartially. This doesn't just mean that he will be hard-working; it is a matter, rather, of willingness to rethink, to re-appraise, to spend as long as it takes on the detail that might be fatal, to give as much thought to the last one percent as to the rest. The genuine inquirer will be ready to acknowledge, to himself as well as others, where his evidence and arguments seem shakiest, and his articulation of problem or solution vaguest. He will be willing to go with the evidence even to unpopular conclusions, and to welcome someone else's having found the truth he was seeking. And, far from having a motive to obfuscate, he will try to see and explain things as clearly as he can.
