Whereas the notion that individuals have 5 fundamental human senses is usually thought of a common reality and might be traced again to Aristotle’s De Anima (On the Soul), many philosophers and neuroscientists at the moment are debating whether or not we could have wherever from 22 to 33 totally different senses.

Amongst these lesser-known senses are equilibrioception, which is related to our sense of stability; proprioception, which permits us to know which components of our our bodies are the place with out trying; and chronoception, how we sense the passing of time.

And that’s simply people. “There are senses that different species have that we don’t, like directional senses and magnetic senses,” says Tok Thompson, professor (instructing) of anthropology. Iron oxide within the stomach of honey bees, for instance, can detect adjustments within the Earth’s magnetic area that allow them to navigate to their hive.


Then there may be the hotly debated existence of the so-called “sixth sense.”

“The ‘sixth sense’ often refers to an ‘unknown’ sense, however now that we all know there are greater than 5 senses, the thought might maybe be higher considered the ‘x sense,’ the place ‘x’ equals the unknown — whether or not some but undiscovered pure sense, or one thing extra alongside the traces of psychic talents,” says Thompson.

In some Indian philosophies, the thoughts, or “manas,” itself is taken into account a sixth sense that coordinates the 5 major senses with different psychological colleges.

Western societies typically equate the sixth sense with extrasensory notion — one thing that in Celtic tradition is historically generally known as “second sight.” Among the many supposed powers of these with the reward was the flexibility to foretell dying, even seeing fish scales (implying a watery grave) seem on somebody they sensed would drown quickly.

Perform a little on-line digging into the sixth sense and one can find myriad claims of life-changing premonitions that seem to defy the concept our 5 senses are our solely colleges of notion.

Amongst them is the internal voice that Wall Road government Barrett Naylor claimed saved his life — twice. Based on a 2009 e-book about premonitions by doctor Larry Dossey, Naylor was heading to work on the World Commerce Heart on Feb. 26, 1993, when one thing instructed him not to enter the constructing. Later that day, it was bombed. That very same intuition, Naylor claimed, additionally saved him from the 9/11 terrorist assaults in 2001. However a perception in mystical, psychic talents isn’t required to imagine that our perceptions can prolong past the bodily senses.

“There are lots of layers to the thoughts,” says College Professor Antonio Damasio, professor of psychology,philosophy and neurology, and David Dornsife Chair in Neuroscience. “Information, actions, emotions — all these contents might be retrieved, however are usually not equally accessible. Some are primarily shrouded in darkness, making aware entry to them tough.”

In consequence, Damasio notes, our unconscious thoughts can instantly present us with a solution after we least count on it.

“Instinct will not be a fantasy; it calls consideration to the richness of our minds,” he says.


Seeing what others don’t can typically require a catalyst. In lots of indigenous cultures, psychedelics are ingested to induce ecstatic experiences that convey revelations. The mushroom Psilocybe mexicana is regarded with such awe by Mexico’s indigenous communities that the Aztecs dubbed it “teonanacatl,” or “God’s Flesh.”

Visions, primarily these introduced on by lysergic acid diethylamide, or LSD, have additionally been the main focus of scientific examine. A chemical compound by chance invented by Swiss researcher Albert Hofmann in 1938, LSD induces highly effective, emotional hallucinations.

After all, LSD finally discovered its approach into the counterculture, and its potential to encourage visions of an interconnected world helped energy the nascent environmental motion of the Sixties. Nonetheless, the drug’s potent results additionally triggered quite a few tragic outcomes.

Researchers at the moment are evaluating the potential for microdoses of different hallucinogenic substances resembling psilocybin mushrooms to assist individuals affected by PTSD, melancholy and nervousness.


Not all visions require chemical prompting, nonetheless. Catholic saints who claimed to have placing visible or auditory hallucinations usually lived piously in non secular orders. Saint Catherine of Siena is alleged to have had her first visitation from Christ on the age of 5 or 6. These in deep, meditative states typically inform of encounters with gentle beings or different unusual, visible phenomena.

These days we’d assume that these kinds of visions, if not induced by mind-altering substances, are the product of a mind dysfunction like schizophrenia. However even in medieval instances, the church questioned the authenticity of such visions and imposed strict guidelines to guage a imaginative and prescient’s legitimacy.

“That is nicely earlier than psychiatry, after all, however individuals dwelling throughout this period nonetheless acknowledged loopy once they noticed it,” says Lisa Bitel, Dean’s Professor of Religion and professor of faith and history. “If somebody was mentally ailing, their visions wouldn’t be taken severely. You needed to be well-regarded locally and no matter you noticed needed to be doctrinally right. A declare that you just noticed the Virgin Mary using in on [the medieval equivalent of] a celestial skateboard wouldn’t be taken severely.”

For the religious, the trendy argument that seeing angels is definitely proof of madness, or on the very least the results of an overactive creativeness, seems absurd. The religious imagine that an individual who has non secular visions has gained particular entry to the reality, not misplaced their thoughts. “They’d say that the enlightened individual is definitely seeing issues as they are surely,” says James McHugh, professor of faith.

Visions are nonetheless a frequently occurring phenomenon, regardless of our supposedly extra rational method to the world, says Bitel. At this time’s reported sightings of UFOs, typically mentioned to be inhabited by celestial beings bearing smart phrases, would possibly simply be the descendants of yesteryear’s angels.

“Cultural phrases could have modified, however the apparitions go on,” she says. “The visions we hear about are simply the tip of the iceberg.”
