I cannot agree more, and of course this same logic holds for the false statements you have just made concerning the philosophy of Ayn Rand. For example, you fault Rand for holding "uncertain axioms" but, if I take you at your word, how does her approach from "uncertain axoims" then differ from the "uncertain axioms" upon which you base the argument in favor of the philosophy of mysticism ?
That's a very good question. SelfAdjoint rightly makes the point that it doesn't matter what the answer to it is as far as your argument is concerned (or, as my grandmother used to say, two wrongs don't make a right). But still, if it cannot be answered then mysticism is bunk. This is because mystics claim to know what is is true, not that they have a good theory or hypothesis.
Aristotle wrote, and I think all philosophers agree, that the most certain kind of axioms we can have are those that are self-evident. Self-evident knowledge can only be knowledge of oneself. This can be seen from the fact that it is not self-evident that solipsism is false. If it cannot be self-evidently known that anything apart from ourselves exists then self-evident knowledge can only be knowledge of ourselves.
It might be objected that it's self-evident that things apart from ourselves exist. However, even physicists are now agreed that naive realism is false, things are not as they appear to be, and this alone makes it impossible to argue that solipsism is self-evidently false, even in the weak sense of 'almost certainly false'.
Self-evident knowledge has to be known to us by means other than our phsyical senses or by our reason. This is because it is self-evident that both our senses and our reason can deceive us. We might be dreaming, insane, confused, ignorant, deluded, in the Matrix, being fooled by Descartes' evil demon and so on. So any axiom based on knowledge acquired solely by means of our senses or our reason is not self-evidently true.
Does Ayn Rand takes it as axiomatic that consciousness is caused by brains? The result can only be a pack of cards. However when Descartes chose "Cogito" he chose a self-evident axiom. Exactly what he meant by "I" is an interesting question but not important here. We know what he meant. It was self-evident to him that he knew some entity he thought was himself thinking really did exist, and really did exist even if it turned out that solipsism were true. This is self-evident knowledge. (With a qualification that isn't relevant here).
This makes some sense of Aristotle's comment that "true knowledge is identical with its object", that there must be an identity of subject and object, knower and known, in the case of true and certain knowledge. If all we can know for certain is knowledge of ourselves then all that can be known is the knower. Here the flavour of the words become more 'mystical'-sounding, but it's just everyday epistemology. True knowledge is knowledge by identity because that's the only kind that can be self-evident. This knowledge may be called immediate, unmediated or direct, knowledge by acqaintance, or 'non-intuitive immediate knowledge' in some meanings.
Such knowledge can't be self-evident to anyone else of course, if it's your knowledge. We can't know what someone else does or does not know. We cannot know whether someone else knows anything at all. Whatever Descartes thought it's not self-evident to me that he ever existed. Zen masters repeatedly warn that knowledge cannot be borrowed. It's a sort of cosmic joke, the only true knowledge is the kind that cannot be communicated.
Your question can be addressed more mathematically as well, by reference to the incompleteness theorems, Goedel's infinite regression of metsystems and so on, if you're into that sort of thing. But that's a can of worms. It can also be answered more philosophically, by reference to Plato's cave allegory.
Does that answer the question? I hope so. It is impossible to take mysticism seriously if one thinks that mystical knowledge can only be uncertain or is irrational. In mystical practice, in Buddhism, Taoism, Essenism, Advaita Vedanta, Sufism, Christian mysticism and so forth, aka the 'mystical religions,' one either knows something or one does not. One can conjecture, or course, but philosophising is not considered a substitute for knowing, and in Sufism is actually discouraged as leading to nothing but confusion. There is no talk of competing theories. Knower and known are ultimately one, and knower and known together constitute all that there is. Thus mystics speak of omniscience without breaking Aristotle's rule of identity.
And, what of the "uncertain axioms" used by Aristotle's to conclude that "knowledge is identical with its object" ?, and thus the "uncertain axoims" applied by Descarte to form his 'cogito' ?. In fact, Rand rejects both of these so-called approaches from "uncertain axioms"--although it is true she is much closer to Aristotle than Descartes.
We cannot know how Aristotle arrived at his conclusion, but I think if you spend ten minutes considering what you know and how you know it you'll reach the same one. "Mystical knowledge" is a grand phrase, but it may, I think, mean only knowledge by identity, and that includes simple stuff like "cogito," or "I'm hot". More generally, it includes "what it is like," which in consciousness studies is the most common definition of consciousness. You yourself know 'what it is like' to be you, having whatever experiences you are having at some time. These experiences may or may not be delusions, in some sense, and for the most part they are according to mystics, nevertheless you know that you're having them. That's mystical knowledge. To get more you just go deeper. As Les says, there's only one way of investigating the nature and source of love. The same goes for the nature and source of knowledge, the problem of how human beings know things.
Let us assume that Rand-woman meets Mystical-man, what type of philosophy would they hold, and why would they hold it ? What would they have in common ? If I can get at this, perhaps I will better be able to form an opinon about the logical possibility of mysticism as a route to knowledge.
The odd thing about the mystical view is that it does not contradict any of the main competing views but encompasses them. It is a meta-view, sometimes called the view from nowhere. It is only a whisker away from materialism, but just as close to idealism. It is not theistic, but if Rand-woman asserted that that God existed Mystical-man would not disagree. The truth is explained as being more subtle. Neither do mystics have any argument with science, except where science over-reaches itself and makes metaphysical assumptions. They've been arguing that naive realism is false since the dawn of recorded human history, and quantum cosmologists are coming ever nearer to the view given by the writers of the Upanishads, as Schroedinger argued a century ago. The proof of the incompleteness theorem just further confirms that view. If Western philosophy has made no progress since Plato then that is just what one would expect to be the case if the the universe is as described in the mystical literature.
I feel there's no problem showing the "logical possibility of mysticism as a route to knowledge." It can be done by the straightforward use of logic even if I haven't managed to do so here. However, showing that mystical practice really
is a route to knowledge is another matter. For logical and practical reasons this is something that one can only do for oneself. Happily, it is repeatedly claimed in the literature that anyone can do it.
