The Original Evil Genius

“Cogito ergo sum”

“I think, therefore I am” stands as one of the most well known statements in the history of philosophy, representing, to its creator, the sole truth we can be sure of. In reaching his epoch-breaking conclusion, Descartes followed every path available to try to disprove it. As the one statement that he believed humanity could prove, no matter what, he had to ensure that it stood to the utmost scrutiny. While putting it to the test, he abandoned the realm of what we might call realistic and hypothesized a few extraordinarily, on the surface, ridiculous ideas.

No, not this evil genius

One of these theories, representing the furthest extent of Descartes’ theorizing, was the Evil Genius theory. It essentially posited the existence of some being that deceives us in all things, forging an entire world that is nothing but an illusion designed to trick us into accepting it as reality. The idea struck me, and I decided, though it does not represent my true beliefs about epistemology(not at the outset of this post, at any rate), to do some theorizing myself and examine and understand what the basis of such an idea would be, if any.

Firstly, we must realize that the ‘reality’ we perceive is unknowable – whether or not there is some objective reality, there is absolutely no way of knowing that. All information about the outside world must, at some point, come through our senses and be processed by our brain, whereby any hope of reliability is obliterated. Thus, it is entirely plausible that everything we experience is simply an illusion implanted into us by some deceiving evil genius – true or not, we would have no way of knowing.

We must not, however, confuse our terms of external realities – everything is external. Our bodies are external. Our brains are external. No piece of information that is based in any external stimuli or information can assure us of its reliability, and thus, even our own knowledge of ourselves is subject to skepticism – how can we be sure of even our own bodies when all we know of them is relayed as signals, via our nerves, to our brain and then to our mind? Every action we take and every sensation we feel could very well be the product of some false stimuli fed to us by this Evil Genius.

“But…what then?” I hear you say. “Doesn’t that mean everything could be part of that illusion? How could anything be real?” These are the same questions Descartes asked himself. But – and this is exactly how he reached his final conclusion – he reasoned that even accepting everything we know of the world and everything we know of reality as nothing but illusion, there still must be something to perceive that illusion. To deceive, something must be being deceived – and thus we must all, on some level, no matter how base or primal or fundamental, exist.

But – and here I depart from Descartes`axiom – that prompted another question: what about reason? We can accept that all knowledge of things outside our minds is subject to unreliability, given the potential for illusion, but what about ideas and knowledge that are derived entirely within our own minds? Are these, too, subject to questioning and skepticism?

I see several answers to this question. Firstly, no – reason and logic are by definition flawless, and pure logic in a field like mathematics is only flawed to the extent that the logic is compromised by the logician. Secondly, yes – this evil genius we speak of must also have the power to twist thought and logic, thus making even reason unreliable. And thirdly, an answer purely from my own interpretation, both yes and no – reason and logic are flawless, but their foundations may be quite the opposite, evil genius or not.

Reason is, at its heart, a construction of building blocks, an endless chain of cause and effect, of premise and conclusion, that leads from one idea to another. Done properly, reason can form an unassailable edifice of thought upon which any attack would break. But while the walls reason erect may be strong, we must consider what it is built upon.

Just try taking out the bottom piece. I dare you.

Reason is, of course, dependent on the assumptions we make and the conclusions we can prove, and to a very large extent strives to limit the former while expanding the latter. But at a certain point, there had to be a jump from nothing to something – there had to be a first premise, a first assumption, and a first idea. Without any logic leading to it, it would be unquestionable – how can you argue against a conclusion created out of thin air when you have no other conclusion to compare it to? This first thought, unreliable as we might find it today were it to be identified, would have to lay a foundation for all successive thought to be build upon. The obvious problems this raises are compounded even further once one realizes that this first thought would likely be an inference made on the basis of experience and reality – and thus, the Evil Genius worms his way into our very way of thinking.

What, then, have we established with the exploration of this idea? Firstly, anything that depends on the senses or processing into the mind from the outside world is unreliable, subject as we are to illusion and deception. Secondly, reason too must be questioned, as the possibility remains that some evil genius would be able to manipulate our logical processes just as easily as he would manipulate external realities. And thirdly, even if the above is not true, reason is still to be questioned because of the first, fundamental assumption or conclusion all else must be based on.

While Descartes’ basic idea – I think, therefore I am – still holds in the face of all that(something must be being deceived, even in the face of all this deception), we have to wonder what exactly the point of all this is. Essentially, we have proven that no piece of knowledge, whether of reason or of reality, is reliable. Really, a more unhelpful and useless conclusion has never been reached. True knowledge, it seems, is nowhere to be found – and because of that, we must accept the flawed, unreliable knowledge that we have and make do with it. Reality itself may be questionable, but so long as we exist within some reality -and Descartes established that we do – we are forever bound to exist within that framework, true or not. Let us not be so caught up in matters of absolute truth and reality. When we can trust nothing as true, we must accept what we have, though forever vigilant against the flaws in that knowing. Be careful about what you believe – the Evil Genius is out there.

  1. Could the question of one’s existence even be posed if we did not already have the language to pose it in?

    • A question that pokes at the idea of just how much we are able to formulate ideas without true expression. A good example of how you can’t have knowledge without it being twisted or processed, and so, corrupted, in some way.

  2. Another very good post. Philosophy 12 must be good times.

    You write:

    “Firstly, we must realize that the ‘reality’ we perceive is unknowable – whether or not there is some objective reality, there is absolutely no way of knowing that.”

    I’m enjoying the role of a contrarian of late and I’ve been harping on the same things. This comment is short and sweet and (hopefully) stimulating.

    Whether or not there is some objective reality, there is absolutely no way of knowing that. Okay. Again it might depend on how ‘objective’ is being defined. But isn’t that statement in itself, a claim to knowledge about objective reality – I KNOW that objective reality is unknowable.

    Is that not similar to the deep self-referential problem that plagued Kant’s epistemology and his distinction between the phenomenon and the noumena? The noumena is unknowable in and of itself, which ends up being a claim to knowledge etc. Again, it is a problem to make a claim that refutes itself in the very act of stating it (eg. I can’t type a word of english, or ‘I know that ultimate reality is unknowable’)

    Do you get what I mean? Fair or unfair?

    • I understand what you’re saying…it is an issue. Still, though, you can accommodate that question by simply saying “We can’t know if ultimate objective reality is knowable or unknowable”. Actually, that statement of not being able to know is an assertion in itself. Perhaps “We do not know whether or not objective reality is knowable”? And given that, we must assume it is not, because without know then…we…don’t know? I guess you sort of get into this endless loop of knowing and knowing what you know you don’t know and all that. Certainly a question to consider. Thanks!
