An essay on individuality, the
concept of self, initiates Dr. Lewis Thomas’ set of essays on science. Coral polyps and fish
recognize their individual natures. Thomas claims this
concept of selfness protects one organism from others. Yet, selfness is not always clear. The title of the book is based upon the relationship between a species of sea snail and the Medusa jellyfish. Living symbiotically, the snail and jellyfish also maintain their distinct identities. Thomas believes they exist in a category of other, not actually as selves.
The concept of the whole versus its parts is continued into the next chapter and is repeated later in the book. Thomas is intrigued by this idea of the contemplation of a whole entity and not its parts. He takes this notion further and relates it to community versus the individual. Some people rail against community and its notion of interactive helpfulness.
A draft of a possible commencement speech continues Thomas’ focuses on group dynamics. Importance is placed upon a group goal, the purpose gained by joint activities. Dr. Thomas wonders what our goal is as humans.
Before we achieve a goal, we need to accept a common view of disease cures and preventions. There are common lifestyle changes and dietary modifications, but odd claims still remain an acceptable alternative for some. As a physician, Dr. Thomas has the
knowledge to discuss health care. He claims health is linked to such diverse entities as radio, television, publishing and sports via advertising, articles and the emphasis on exercise. Unfortunately, we are being fooled into believing we humans are very delicate, constantly susceptible to disease, desperately dependent upon a medical system, according to Thomas. He continues by saying that the happy truth is humans are strong, resilient beings.
Dr. Thomas also rejoices in the creation of DNA and its ability to mutate. Without this ability, he states, there would be no evolutionary process. This same notion is used in Thomas’ argument against cloning. There would be a lack of change inherent in the resulting organism.
The doctor’s love of change is echoed by his fascination with etymology, the history of words and their changes. The word, Virus originated in Old English, as to flow or ooze. Thomas explains that warts and viruses are linked, in that certain wart cells enable virus reproduction. According to Dr. Thomas, warts should not be a source of worry. However, humans are filled with worry. The author reacts by including an amusing chapter regarding this trait.
Dr. Thomas does worry, about the education doctors are receiving. One of his book’s last chapters is devoted to the need for the liberal arts to become prerequisites for medical school. Knowledge of how humans have lived is important. Also important to Thomas is an increase in scientific investigation. He believes this is vital for human survival.
This book pushes for more science education. Dr. Thomas is an excellent advocate. His message is consistent, he shows amazing interest in his subjects, and has incredible knowledge.
