“According to Stoic philosophy, when we assign intrinsic values like “good” or “bad” to external events, we’re behaving irrationally and even exhibiting a form of self-deception. When we call something a “catastrophe,” for instance, we go beyond the bare facts and start distorting events and deceiving ourselves. Moreover, the Stoics consider lying a form of impiety—when a man lies, he alienates himself from Nature.”
