The word 'satanic' can indeed be properly applied to all negation and reversal of order, such as is so incontestably in evidence in everything we now see around us: is the modern world really anything whatever but a direct denial of all traditional truth? At the same time, and more or less of necessity, the spirit of negation is the spirit of lying; it wears every disguise, often the most unexpected, in order to avoid being recognized for what it is, and even in order to pass itself off as the very opposite of what it is; this is where counterfeit comes in; and this is the moment to recall that it is said that 'Satan is the ape of God', and also that he 'transfigures himself into an angel of light'.
In the end, this amounts to saying that he imitates in his own way, by altering and falsifying it so as always to make it serve his own ends, the very thing he sets out to oppose: thus, he will so manage matters that disorder takes on the appearance of a false order, he will hide the negation of all principle under the affirmation of false principles, and so on.
Naturally, nothing of that kind can ever really be more than dissimulation and even caricature, but it is presented cleverly enough to induce an immense majority of men to allow themselves to be deceived by it; and why should we be astonished at this, when it is so easy to observe both the extent to which trickery, even of the crudest sort, succeeds in imposing itself on the crowd, and also the difficulty of subsequently undeceiving them?
Vulgus vult decipi was already a saying of the ancients of the 'classical period', and no doubt there have always been people, though never as many as in our days, ready to add: ergo decipiatur!
