Jagadish Chandra Bose was one of the first scientists in the world to undertake interdisciplinary research by looking at plants from the vantage point of physics.

He subjected plant and animal tissues to various kinds of stimulus, and found that they all showed an electric response. Finding that this reaction occurred in metals as well as plants and animals, he then proceeded to study the differences in response under various conditions.

He found that all materials are numbed by cold, intoxicated by alcohol, wearied by excessive work, stupefied by anesthetics, excited by electric currents, stung by physical blows, and killed by poison. They all exhibit essentially the same reactions of fatigue and depression, together with the capacity for recovery and strength, and also permanent unresponsiveness, or death. All materials are responsive or unresponsive under the same conditions and in the same manner.

His investigations showed that in the entire range of responses - regardless of whether the subject is metallic, plant or animal - there are no exceptions. The living response, in all its diverse modifications, is a repetition of the responses seen in the inorganic. Further, the nature of the response is determined not by the play of an unknowable and arbitrary vital force, but by laws that do not change, and act equally and uniformly throughout both organic and inorganic matter.

This realization was always at the core of his work. He sought to show that all materials react to their environments according to the same laws; in other words, everything exists in the same field of consciousness.

This book was originally published in 1902.

Reviews

"This work outlines some of his greatest work, the thin line between living and non-living material. This timely reprint is a testament to a remarkable man whose achievements in science beggar belief to this day."

"Bose is one of those geniuses who has been lost in history. I hope that anyone looking to expand their minds will enjoy the great adventure this read is."
