Since ancient times, it has been widely accepted that humans have five senses: touch, hearing, smell, sight, and taste. However, scientists are increasingly agreeing to question this concept, in order to bring the number of senses to nine!
The five senses of the human being is a notion in force since the Treatise on the Soul (Book II), a work of the famous Greek philosopher Aristotle. At the time, the senses identified were considered as a set of capabilities to identify and obtain information about our environment to better apprehend it, that’s why it was a question of “external senses.”
More than 2000 years later, scientists now admit that we have not five but nine senses. What are they?
According to François Le Corre, doctor specialized in the senses at the University Pierre and Marie Currie and author of the thesis entitled Distinguishing the senses: individuation and classification (2014), there are four other so-called “internal” senses that we use also:
He explains that “the experience we have of our world, or our direct environment, is not one-sided but rather multisensory”, and states that he discovered that “auditory perception can be strongly influenced by visual perception, or that auditory perception could influence our taste perception”.
François Le Corre also said that science had “neglected the so-called internal senses for too long for the so-called external senses, because they are observable,” and that now there is “a broad consensus among scientists of the “hard science” type in favor of the hypothesis that there are more than five senses “.
Thus, the four internal senses to be added to the five external senses are thermoception, nociception, proprioception, and equilibrium. Thermoception is none other than the ability to feel temperatures, nociception makes it possible to feel pain, proprioception (or kinesthesia) is the capacity to locate our own body parts and finally, equilibrium is the sense that allows ud to maintain our equilibrium.
If these faculties are obvious to all, we must know that from now on, these are considered as full senses.
