The study of fallacies can be pursued in at least two different ways. It can be approached traditionally; in which case one defines, explains and exemplifies ways in which unsound arguments can be made to appear sound. Or it can be approached deeply, in which case one relates the construction of fallacies to the pursuit of human interests and irrational desires. Using the first approach, students gain little by memorizing the names and definitions of fallacies. They soon forget them. Their minds are left largely untouched and therefore unmoved. On the other hand, the second approach make possible the acquisition of lifelong insights into how the mind every uses unsound arguments and intellectual tricks to further its ends.
