The Professor: The Opinion We have confused criticism with cruelty, honesty with humiliation, and intellectual courage with the public destruction of another person's dignity. That confusion is not merely a failure of etiquette; it is a failure of leadership, pedagogy and, ultimately, civilisation. There is a profound difference between correcting a person and conquering a person. The purpose of criticism should be transformation—not triumph. It should expose what is deficient without denying what is valuable. It should illuminate the error without reducing the human being to the error. The mature critic asks: How do I make this person, this institution, this idea or this society better? The immature critic asks: How do I demonstrate that I am superior? That distinction changes everything. Criticism performed publicly often becomes theatre. The audience becomes part of the punishment. What began as an attempt to correct a weakness gradually becomes a performance of intellectual superiority. The critic is no longer interested in whether the message is received; they are interested in being seen delivering it. And therein lies the danger. A criticism that destroys the possibility of dialogue has defeated its own purpose. This does not mean that we should become soft, evasive or intellectually dishonest. Quite the opposite. We need a culture capable of radical honesty without unnecessary humiliation. We must be courageous enough to say, “This is wrong.” But we must also possess the discipline to explain why it is wrong, what consequences it produces, and what a better alternative might look like. Truth does not become more truthful because it is shouted. Nor does an argument become stronger because another person's dignity has been diminished. The strongest intellectuals I know are not those who can find the most sophisticated ways of embarrassing people. They are those who can enter difficult conversations without surrendering either truth or humanity. There is also something deeply philosophical about the principle: Criticise in private. Appreciate in public. Public appreciation affirms dignity. Private correction creates a space in which transformation is possible without the theatre of embarrassment. It allows a person to listen rather than defend themselves. It separates the person from the problem, making it possible to confront the latter without unnecessarily destroying the former. But there is another dimension we often overlook: appreciation itself is a form of social investment. When we publicly acknowledge someone's contribution, discipline, improvement or courage, we do more than flatter them. We establish a culture in which excellence becomes visible and therefore reproducible. We tell others: This is what we value here. A society that publicly celebrates achievement but privately tolerates corruption of character has a contradiction at its centre. Likewise, a society that publicly humiliates failure while privately rewarding arrogance teaches people to conceal their mistakes rather than learn from them. That is why this principle extends far beyond interpersonal relationships. It belongs in our classrooms, boardrooms, universities, families, workplaces, political institutions, churches, civic organisations and communities. Our institutions are increasingly becoming spaces where people compete to expose one another rather than environments where people collectively improve one another. We have developed an appetite for the spectacle of someone's failure. We screenshot mistakes. We circulate embarrassment. We weaponise ignorance. We publicly dismantle people for the pleasure of being right. And then we wonder why people are afraid to ask questions, admit mistakes, experiment, innovate or acknowledge that they do not know something. A culture of humiliation produces concealment. A culture of constructive criticism produces learning. – at Tembisa, South Africa
