There are many moral problems in healthcare, one of which is telling the truth. It is strongly believed that a doctor must tell the truth to his patient, to respect the patient's autonomy. But aren't there cases in which telling the truth can be harmful? Can we conceive of a world where lying is not allowed? A study of Immanuel Kant's arguments about truth-telling in general, then an analysis of Joseph Collin's ideas about truth-telling in healthcare, might help us better understand the different questions that arise from this issue. Kant defends the principle that we should never lie, even if doing so might prevent death. He believes that the expression "having a right to the truth" has no meaning and argues that people should rather say that a man has a right to his own truthfulness (603). For him, truth in statements that cannot be avoided is a man's formal duty, no matter how grave the consequences (603). According to him, what jurists believe to be a lie, that is, an intentionally false statement towards another man that is intended to hurt another, is incorrect because a lie always hurts another (604). He believes that anyone who tells a lie, no matter how good his intentions, is responsible for the consequences and must pay the price (604). He argues that being sincere in all statements is a “sacred unconditional command of reason” (604). In contrast, Joseph Collins has a different point of view in his presentation. Choose a negative answer to the question “Doctors should tell patients the truth.” He believes that telling the whole truth often means committing a cruelty of which many are incapable (605). He divides patients into four categories of people: those who want to know the truth... try to be more realistic and talk about what their experiences are. For Kant, lying is always wrong while Collins believes that lying contributes to the success of the doctor's work. Kant is more severe on the subject. However, Collins' perception of the topic may be more appealing to people because it engages the reader. Doctors focus on the well-being of patients and if they think that not telling the whole truth helps them, it should not be considered wrong. Works Cited W.
