I share your view, Aeon. As with any classification, reality is seamless and transitory, not fixed around discreet levels. I think the concept of "baseline conciousness" is a good one. To me it suggests that a individual is free to climb the evolutionary spiral, but will do this as a salmon going upstreams from the river of the collective (un)conciousness. In other words, achieving the level of conciousness of the Buddha/Christ/insert favorite historial or mytical person, was truly heroic and unique in their times, when the collective maturity was much lower.
What I find appealing with the message of Thelema is that to me it saying that the baseline has shifted so much that today, it is possible for ALL to achieve that direct, personal contact with our inner divinity. We don't need an elite of masters to tell us what to believe. But it still takes hard and determined work, regardless of what "system" we use. In reality, this is still virtually impossible for most people on this planet, who are still struggling to fill their basic needs of survival, or who are imprisoned by fundamentalist oppression. In a way we who do have the possibility should perhaps also see that as a responsibility, not to waste it on "false gold".
Crowley dedicated his life to the cause of assisting the transition of the collective conciousness into a higher level. To me, this says something about the level beyond the K&C. It "hints" that beyond the fully developed ego-conciousness, there is the realization that the personal Will is like an instrument in an orchestra (for lack of a better metaphore). -We can practice and fine tune it to perfection, but if the rest of the orchestra is playing awfully off-key, the gain is still, from this expanded point of view, very limited.
