The paper "Ethical Duties Towards Others: Truthfulness by Kant" is a good example of a book review on philosophy. The maintains that telling the truth is of monumental importance in determining the meaning of a conversation. Here, the author continues to illustrate that failure to incorporate the truth in the conversation makes the entire conversation valueless. A liar is also said to destroy fellowship. This implies that liars are held in contempt because they undermine the value of a conversation and destroy fellowship, which relies on the truth. The key reason as to why people result in lying is either to conceal the real self or to conceal some faults such as weaknesses (Kant, 1930).
A man who tells the truth is said to be a man of good principles and integrity. Since people hide the truth so as to remain reserved, the writer maintains that there would be no need for reservation if all men were good. I agree with the writer because the information given confers with the modern world and activities that people experience on a daily basis. Lying is one of the most common causes of conflicts among people.
Therefore, the writer is providing relevant information. In addition, I agree with the writer especially because of the outlined consequences of lying, which are correct. Lairs are some of the individuals held with the highest level of contempt in society. I also agree with the writer because of the accuracy. As far as the presuppositions are concerned, the writer presupposes that if men were tasked with the role of raising children, they would take longer before they learned how to speak.
In addition, the writer makes the claim that if all men were good, there would be no need to remain reserved.
