Summary of: Mere Christianity
By: C.S. Lewis


Embark on a thought-provoking exploration of universal moral values and the existence of a higher power in this summary of ‘Mere Christianity’ by C.S. Lewis. Delve into the human nature of quarreling, the consistent moral values across cultures and history, and the implications of these moral values on the debate between materialism and spirituality. The summary will also challenge you with Lewis’s trilemma about Jesus’s divinity and provide insights on Christian virtues and the relationship between evolution and Christianity.

The Moral Law of Nature

Every human being has an inherent understanding of the universal moral law, which guides their behavior. Our love for quarreling is a testament to the fact that our disputes arise from a perceived violation of this moral law, such as fairness or honesty. Even when individuals break moral standards, they still intuitively feel that they have acted in the wrong. This moral law of nature differs from the laws of physics but should be thought of as a universal standard for ethical and decent behavior.

Universal Moral Law

The author believes in a universal moral law that all humans share, but cultural relativists disagree. They argue that standards of behavior are learned from society and vary across cultures. However, the fact that we have to learn moral values doesn’t mean they’re not true and consistent across different times and cultures. Historical examples of seemingly different moral systems are often just immoral behaviors. Instead, the values of different cultures have more in common than they differ. By looking at history and anthropology, we can see that the moral law is not an arbitrary human invention, but a timeless, real thing.

The Moral Law and the Existence of Theism

The existence of moral law is a strong indication of the existence of a higher being or consciousness that created the universe. Unlike science, introspection is the method of identifying the reasons that govern our actions. Our realization is that this reason is a powerful, uniform force we know as the moral law. Materialism, which believes the universe is a chance product of matter, has no explanation for the moral law. Therefore, it is difficult to imagine how this opaque world can be interested in humans. Nonetheless, the existence of moral law finds a home in theism and suggests its presence. In summary, the presence of the moral law indicates a probability of divine existence, especially against the backdrop of materialist perspective.

Lewis’ Trilemma Argument

The author presents a convincing argument in the form of a trilemma regarding Jesus’ claim of divinity. It outlines the three options, including that he was a liar, delusional, or truly divine. Based on his life, character and teachings, the most likely option is that he was divine.

In his book, the author presents a compelling argument based on a trilemma about Jesus’ claim of being divine. The trilemma focuses on the three possibilities regarding his claim- he was telling the truth, consciously lying, or delusional. The author argues that the most likely option is that he was divine.

Although some may argue that he was just a moral teacher, the author rejects this option as it would mean he was either lying or delusional, which is not morally acceptable. Based on his modest life and his teachings, it is impossible to imagine that Jesus was simply manipulating people for personal gains. Similarly, in every other aspect of his life, he exhibits great sense and intelligence. There’s no indication that he was not in his right state of mind, making it difficult to believe that he was delusional only in this specific area.

Therefore, it is most likely that Jesus was divine. This conclusion is based on the life he led, his teachings, and his character. His virtues of humility and honesty do not align with someone who is incredibly arrogant and proud to claim to be divine when he is not. The author’s reasoning and logic are compelling and provide a new perspective on the debate around Jesus’ divinity.

Overall, the author’s argument is well-structured, easy to follow, and provides insight into a complex topic. The trilemma approach offers an interesting way to analyze the claim of divinity and contributes to the ongoing discussion of Christianity.

Understanding the Christian Concept of Evil

This summary explores the Christian perspective on the problem of evil. The author presents the idea that evil in the world stems from human free will, which corrupts the goodness that already existed. The key message is that evil is always a secondary and parasitic force on the good. The author argues that true freedom requires the possibility of making immoral choices, even though this means that some people will inevitably make the wrong choices.
