Abstract
This chapter focuses on one of the common fallacies in Western philosophy, 'the line‐drawing fallacy'. Many logic or critical thinking textbooks treat the line‐drawing fallacy as a footnote to or subcategory of another fallacy. They view it as a variation of vagueness, false dilemma, slippery slope, or the perfectionist fallacy. Depending on how one interprets a key premise or central term of the argument, detecting a line‐drawing fallacy can take several forms. The chapter discusses these forms. To correct or to prevent the absurd conclusions, logicians try to identify and/or explain the nature of the line‐drawing fallacy. Several line‐drawing‐related fallacies immediately arise, from false dilemma to straw man. Yet this exercise is too obvious to help a student discern the underlying difficulty in recognizing the line‐drawing fallacy or avoiding the paradox it raises.
