Seeking to clarify the concept of lying, I deal with several topics on which ideas vary. I consider the symbolic, intentional, misleading, and relational character of lies, and include secrecy and other forms of deliberate deception within lies on the basis of these components. Next, I distinguish between human and nonhuman deception, invoking the concepts of symbols, role‐taking, self, and mind. Following this, I present several representative categories of the infinite array of benign and exploitive social contexts in which lying occurs. In a brief discussion, I then impugn the commonly‐used notion of “self‐deception” as internally contradictory. And, finally, I describe both negative and positive consequences of deception in human affairs.
