Lying is Never Justifiable: A Study in Ethics by Henry Clay Trumbull is an important work that explores the moral question of the justifiability of lying. The author considers in detail the ethical aspects of situations when a person may be tempted to distort the truth or provide false information for certain reasons. Through the prism of philosophy and practical examples, the author analyzes why lying cannot be a justified action in any circumstances. This book is not only a theoretical reflection, but also an invitation to independent moral reflection and the choice of principles to be guided in difficult moments. "A lie is never justified: A study in ethics" is not only an invitation for the reader to analyze his own values, but also support in maintaining ethical principles in society.
