Lawrence Joseph Henderson was a physiologist, chemist, biologist, philosopher, and sociologist. He became one of the leading biochemists of the first decades of the 20th century.Lawrence Henderson graduated from Harvard College in 1898 and from Harvard Medical School in 1902, receiving the M. D...

. In the book, Henderson discusses the importance of water
Water
Water is a chemical substance with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state . Water also exists in a...

Life
Life is a characteristic that distinguishes objects that have signaling and self-sustaining processes from those that do not, either because such functions have ceased , or else because they lack such functions and are classified as inanimate...

. The main thesis of the book is that life depends entirely on the very specific environmental conditions on Earth

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets...

, especially with regard to the prevalence and properties of water. For example water's specific heat capacity acts as a buffer to maintain temperatures needed for life, while its polarity
Chemical polarity
In chemistry, polarity refers to a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules interact through dipole–dipole intermolecular forces and hydrogen bonds. Molecular polarity is dependent on the difference in...
