Sound logic is not always desireable. It is, in fact, the most dangerous of all things if one starts with a false premise. In such a case the more logically one reasons, the further one gets from the truth. The only hope there is for a healthy conclusion or a good thought, if the premise is false, is to make a terrible slip somewhere in the reasoning process. Crooked roads sometimes get us back on the right road if we have lost our way, but if the wrong road is a straight road we are lost forever.
