Sceptics regarding the existence of Atlantis have been around since the time of Plato. The first such critic was assumed to be Aristotle, a pupil of Plato’s, who apparently denounced the Atlantis tale as an invention. However, this presumed scepticism of Aristotle has now been seriously challenged by Thorwald C. Franke in a 2012 book, Aristotle and Atlantis^[706] specifically dealing with the subject. Nevertheless, Aristotle does record the existence of a large island in the Atlantic known to the Phoenicians as Antilia, inadvertently supporting Plato’s story⁽ⁱ⁾.

Franke has recently outlined the extensive support for the existence of Atlantis from the earliest times in his recent German-language book^[1255]. He has followed that with a YouTube video^(j) in which he relates how scepticism became more extensive in the 19th century.

>Sprague deCamp was probably the most quoted Atlantis sceptic of the second half of the 20th century. He offered the blunt declaration that Plato concocted the whole story, basing the tale on a mixture of the wealth of Tartessos in Spain, and the destruction of the Greek island of Atalanta all intermingled with the mythology of Atlas.

One of deCamp’s most quoted extracts is that “you cannot change all the details of Plato’s story and still claim to have Plato’s story.” While I fully endorse this comment, I must point out that there is a difference between changing and interpreting details. For example, when Plato refers to Asia or Libya, even deCamp accepted that in Plato’s day ‘Asia’ was not the landmass we know, stretching from the Urals to Japan, but interpreted Plato’s ‘Asia’ as a reference to a much smaller territory ^[0194.27].<

Many modern commentators believe that in the interests of dramatic effect Plato heavily embellished the core truth underlying the story, namely that of an ancient submerged civilisation.

A claim frequently put forward by sceptics was echoed by Ian Alex Blaise, who wrote^(l) that “we can summarise the ‘Timaeus and Critias’ as a parable of good (ancient Athens) triumphing over evil (Atlantis).” This, however, would appear to run counter to Plato’s narrative that records that both vanquished and victorious armies were destroyed!

Another critic, Joe Garcia, offers a paper attacking both the Minoan and Spanish location theories^(m).

However, when we consider modern sceptics we find that they have been provided with unlimited ammunition by the poor scholarship of many Atlantis supporters and the outright ravings of the likes of Blavatsky, Steiner, Cayce, and a profusion of other authors, who claim to have channelled information regarding Atlantis.

Edwin Ramage, in his essay^[522] on Atlantis, makes the interesting comment that “believers tend to overshadow the sceptics for the simple reason that a positive theory, whether it is simple or elaborate, tends to be more attractive and to make better reading than any attempt at refutation, no matter how well taken it may be.” This is probably akin to referenda questions being framed by governments in a manner that favours a Yes vote that will provide the outcome that they want. This is because most people prefer to say Yes rather than No.

However, if the Atlantis narrative has any truth in it, the legitimate criticisms of sceptics must be given due consideration. One such sceptic is Paul Jordan who has produced a highly critical work^[418] on the subject. Jason Colavito is another vocal non-believer and has written a considerable amount on the subject^(d). Several other websites^(b)(c)(e) can also be recommended, in particular,  a seven-part offering by Pat Linse^(b).

I recently came across a sceptic review of Atlantis theories by Justin Spring which I thought contained some novel views and although I totally disagree with his conclusions, I feel it should be given a reading^(g).

While I expect that few sceptics will be reading this entry, I would recommend to anyone a paper by Karla Mclaren, a former New Age ‘believer’ who developed into a sceptic^(f).

A 2015 survey by the Chapman University of California was repeated in 2016, which suggested that nearly 40% of Americans believe that an advanced prehistoric civilisation, such as Atlantis, existed, causing consternation among sceptics^(h). Why they found it so depressing is hard to understand since popular belief is no guarantee that it is supported by reality. After all, it was once commonly thought that the sun revolved around the earth!

There are times when I regret that I have not had a university education and then along comes a qualified academic who manages to remove any such feeling. One of those is Seth Stein, a professor at Northwestern University, who specialises in plate tectonics, who was reported in early 2018^(k) to have proposed that “one of the strongest reasons to dispel Atlantis as a true ancient civilization is the fact that we haven’t found it.” This asinine comment shows a total abandonment of critical thinking because he seems to think that because something has not been found, proves that it does not exist. For example, before Heinrich Schliemann, Troy did exist but had yet to be located. Professor Stein’s stupid statement is also built on a flawed understanding of what Plato said or more correctly, did not say. Plato never described Atlantis as a continent, as assumed by Stein and it can be reasonably argued that our Atlantic Ocean where he sought Atlantis was not the Atlantic ‘Sea’ referred to by Plato. I suggest that Stein sticks to earth sciences and leave Atlantis to others.

In October 2021, Franke published an essay on what he calls the ‘dark side’ of Atlantis scepticism, which offers an interesting overview of anti-Platonism since the time of the philosopher⁽ⁿ⁾.
