Concept
Plant perception (paranormal)
Résumé
Plant perception or biocommunication is the paranormal idea that plants are sentient, that they respond to humans in a manner that amounts to ESP, and that they experience a range of emotions or parapsychological states. Since plants lack nervous systems, paranormal claims regarding plant perception are considered pseudoscience by the scientific community.
Such paranormal claims are distinct from the ability of plants to sense and respond to the environment via chemical and related stimuli.
In 1811, James Perchard Tupper authored An Essay on the Probability of Sensation in Vegetables which argued that plants possess a low form of sensation. He has been cited as an early botanist "attracted to the notion that the ability of plants to feel pain or pleasure demonstrated the universal beneficence of a Creator".
The notion that plants are capable of feeling emotions was first recorded in 1848, when Gustav Fechner, an experimental psychologist, suggested that plants are capable of emotions and that one could promote healthy growth with talk, attention, attitude, and affection.
Jagadish Chandra Bose began to conduct experiments on plants in the year 1900. Bose invented various devices and instruments to measure electrical responses in plants. He stated from his experiments that an electrical spasm occurs during the end of life for a plant.
According to biologist Patrick Geddes "In his investigations on response in general Bose had found that even ordinary plants and their different organs were sensitive— exhibiting, under mechanical or other stimuli, an electric response, indicative of excitation." One visitor to his laboratory, the vegetarian playwright George Bernard Shaw, was intensely disturbed upon witnessing a demonstration in which a cabbage had "convulsions" as it boiled to death.
In 1900, ornithologist Thomas G. Gentry authored Intelligence in Plants and Animals which argued that plants have consciousness. Historian Ed Folsom described it as "an exhaustive investigation of how such animals as bees, ants, worms and buzzards, as well as all kinds of plants, display intelligence and thus have souls".
