If you are an honest person, you are not content to hold beliefs subjectively — because of accidental features of your psychology or circumstances. You aspire to be objective — to conform all of your thinking to the facts. To do this you must be able to identify the available evidence, to determine what conclusions it supports, to check the premises you have already formed, and to integrate your conclusions into a consistent sum. This lecture by philosopher Gregory Salmieri, recorded at the 2014 Objectivist Summer Conference in Las Vegas, discusses these skills and how to develop them.
