So #15 is traditionally - THE DEVIL! Maybe you're spooked of the Devil? Maybe not, I bet you can tell what kind of a person you are if you are or aren't. That's my opinion. Well, that's an aspect of my opinion, there's actually rather a lot to it. Why not explore? Yes lets!
So in some ancient forms the Devil is representative of temptation, think of Christ being tempted in the wilderness for example - the Devil appears and tries to get Christ to act all wrong and then Christ resists. The Devil also appears and tempts Job - "Curse God and Die!" The Devil tempts. Kind of a weird thing to tempt a person to - hopelessness? I can see that, hopelessness is a real vice.
Over time this figure changes into a manichean opposite of god, goes from the Adversary meant to tempt creation into an enemy, possibly even on equal footing, the Devil, to be opposed, thwarted, tossed in the lake of fire. Now this is probably the more familiar of the Devils you've heard of and the Tarot kind of works from that, and it kind of mentions the older meaning too. The Devil represents Vice and the temptation to vice. And this... This is representative of a worldview that may prevail, but I'd say not by many. The idea here is that there is a force that tempts you to the wicked actions - this force is purely malevolent and wants to doom you. Now - I don't buy that. That there is a dark force that turns your hand and heart to wickedness - well I don't deny that. But we're talking about dualism and soul/mind/body divisions - I'm not exactly going that way. It's not a dark spiritual force that tempts you to wickedness - is what I am saying.
Rather, the Devil represents the dooming component of human existence - which is our frailty. Our physical frailty specifically. The Devil represents a kind of arrogance, in my mind, that there is a special force that rules over evil and compels you to evil action. Vice is maybe its own temptation, but I theorize something else.
For example. I see the people driving their $100,000 cars in my neighborhood and you know, I daydream about robbing them, I totally do. Because I want money. Which is gross! But here's the thing - the wolf is at the door, the menace is in the world, there are menacing forces that would drive me to do such things. Or maybe you've grown too attached to someone, you'd rather they were dead than without you, or you're menaced by another who looks to outcompete you, or you've got a vague anxiety that the person you are with is going to be the last person to love you, the last person to touch you. You can have these fears and they'll tempt, tempt or drive you to vice. I don't suggest that people have any innate wickedness but that their fragility predisposes them to it. Not a fall of man - but the story of the fall of man kind of sums this up. The immortal and invincible person is of course the good guy - there is no danger that he faces.
This of course doesn't allow for mad-dog killers and the sort. Serial murderers and ladies that execute their babies in bathtubs. Genuinely I don't think those people are wicked, I think they are probably very crazy and that is sad.
So the Wolves. The wolf is kind of the same as the person - pack hunters, tribal and so forth. We're similar in our ecological neighborhood. But the wolf, you know, they have a few million years of adaptive advantage over us, they're more capable, dangerous - they're more effective and less fragile. They're a paradigm of human fear, a good marker of human frailty. The wolves at the door, the danger that waits lurking. Man is a wolf to other men - the big bad wolf- it comes up and hasn't faded imagery wise.
The wolf means another thing too though.
The beneficence of human genius. Cause the dog is a wolf and it's our best friend. Not mine you understand, but I get it - a dog, you can get somewhere with a dog, it is the primordial danger and fear turned on its head, made a tool. A useful tool to turn against our other predators, other people included. It's a sign that this fragility, while it tempts us to dark deeds - is also a tendency that can be mastered. The frailty endemic to the human condition, that creates the human condition, it can be snatched away and have its nature changed. Because we're better than the world, we can solve the puzzle of biology and darkness and primordial fear.
