Summary of: On Being: A Scientist’s Exploration of the Great Questions of Existence
By: Peter Atkins


Embark on a scientific exploration of the great questions of existence as we delve into the enlightening book summary of ‘On Being: A Scientist’s Exploration of the Great Questions of Existence.’ In the following sections, you will discover why science is the only tangible means we have of understanding our physical world and how it challenges our long-held religious beliefs in the face of hard evidence. Various theories are presented to unravel the mysteries of the universe’s creation, the evolution of life on Earth, and the pursuit of immortality. With an engaging, well-organized, and instructive focus, this piece aims to present complex subjects in a digestible manner for readers aged 20-40.

Science vs. Religion

The book explores the success of using the scientific method in understanding our physical world and how it stands in direct opposition to the religious approach to truth. Scientific experimentation has proven that nothing exists beyond the physical world and theories that rely on the existence of metaphysical phenomena lack objective evidence. Religious belief remains popular as it offers an easy answer to the great questions of existence and meaning, but true knowledge can only be gained through scientific inquiry. Scientists should not shy away from grappling with life’s “big questions,” many of which are discussed in the book.

Unpacking the Complexity of the Origin of the Universe

The question of how the universe came to be has been a subject of debate by religious folks who attribute it to God’s creation and scientists who look to the physical world for answers. Scientists have proposed various theories from multiple universes to the origins of electric charge and dark matter. However, none of these concepts have been proven, and scientists take baby steps in building on previous discoveries. Despite the lack of a single theory, scientists continue to explore and tackle the big questions over generations to answer fundamental questions that religious thinking can’t match.

Journey of Life

The book highlights how theories of evolution and natural selection enlighten the process of the journey of life.

The Australian High-God Karora gave birth to the first man! While this creation story seems fanciful, it’s easy to see how science provides a more credible explanation of how we and everything around us came into existence. Evolutionary theory, backed up by evidence from the fossil record and DNA research, offers a convincing account of the development of life on earth.

Our development process is the result of a junk-war of DNA, with junk-DNA mutating randomly and competing for usefulness in a given environment. Some changes, like the development of useful traits, enhance the chance of survival and increase the chances of passing down helpful DNA to future generations.

The theory of natural selection asserts that useful DNA information such as opposable thumbs or the giraffe’s neck can better survive and thus pass on its useful DNA to the next generation, resulting in progressive development.

Though scientists do not fully understand how life emerged from inorganic matter, numerous experiments have shown how inorganic matter can become organic life. Based on verifiable physical science evidence, there’s no reason to defend creationism or believe that God breathed life into Adam and Eve made from clay.

The journey of life is fascinating and intricate, and understanding the natural processes that drive it can give humankind a better sense of meaning, purpose, and appreciation for the life that surrounds us.

The Science of Reproduction

Have you ever wondered how you came to exist on planet Earth? Science has the answer. Francis Crick and James Watson decoded the secret of how reproduction and trait inheritance work, revealing that it is our DNA that causes our children to resemble us. The replication of DNA is never perfect, and errors can result in diseases, but they also give us the gift of variability across generations. Humans need sexual reproduction because we were not perfectly designed for our environment. Asexual reproduction works for single cells, but random transformations and combinations of DNA information from sexual reproduction bring greater flexibility to cope with the ever-changing environment. Science, not religion or mysticism, explains our existence. Ancient beliefs, such as the Greek story of Aphrodite arising from Uranus’s semen, don’t hold up to scrutiny.
