>Well, it sounds like you went from being an atheist to an agnostic. That certainly is a more rational and less dogmatic position to take, based on what we know.

I'm not sure why this argument shows so often (and it's not even limited to religion), but it's an incredibly bad one. The positions here are not a ternary matter. The options are not limited to 100% one way, 100% the other, or right in the middle.

The 'most rational' position lies somewhere in that continuum. When converting to the usual trinary labels, one extreme or the other may end up being the most rational position. The center is not automatically best.

> I was a staunch atheist before psychedelics, now the notion of a purely material universe seems naive.

Continuing to try to avoid the religion topic directly, I'd caution you against reading too much into your trips, which your excerpt oddly points out as well. Our brains are rather questionable devices for perceiving the world as it really is even when they are functioning properly. There is no reason to believe intentionally screwing with it's functioning would somehow increase it's ability to perceive the world truthfully.

I can see potential value in using trips to improve lateral thinking, and perhaps even for insight into yourself, but in terms of exposing hidden secrets of the universe... There's no rational basis for that, and the most likely explanation seems to be the combination of the intentional misfiring and the usual imperfect operation of our brains.
