Then we come across this line: “What upsets people is not things themselves but their judgments about things.” We sit there in silence, absorbing this two-thousand-year-old nugget, as obvious as it is profound.
And also deeply flawed reasoning unless you believe there is no action or event that could be considered objectively bad, or that all responses to negativity first pass through one's judgment. Someone stabs your face, you respond with instant upsetting pain without first "judging" the incident as upsetting. Or someone, just for instance, starts slowly and violently torturing a newborn baby in front of you. That's not inherently upsetting, eh? Bold claim.
