Whoever was responsible for the idea of dividing self into lower and higher parts committed a serious crime against humanity. This division has given rise to the notion that the lower (ego and immature) self must be overcome while the higher (unitive and whole) self must be sought as the goal of human realization. Out of ignorance, I too clung to this notion because I believed it was this higher self that would be united with God for all eternity. It took a long time before my experiences led me to doubt this conviction and, at the same time, let in the possibility that this was not the whole truth and that there was still further to go.

Doubt, the essential preliminary of all improvement and discovery, must accompany the stages of man’s onward progress. The faculty of doubting and questioning, without which those of comparison and judgment would be useless, is itself a divine prerogative of the reason.

The absurd is a shadow cast over everything we do and even if we try to live life as if it has meaning as if there are reasons for doing things the absurd will linger in the back of our minds as a nagging doubt that perhaps there is no point.
All that the posture of skepticism accomplishes is to freeze the ego in an ignorantist poverty that never stretches or diversifies its resources of imagination or understanding. Any uncultured cretin can close his eyes and try to reduce the issues down to linear simplisms and say, "I am doubting, I am proving my magisterial or sovereign control over my own mind." Doubt is a useful and significant test of one's critical powers, but by itself it bears little if any significant cultural charge of enlightenment or satori; indeed it is the very opposite kind of thing.
In spite of the ancient roots of skepticism--all the way back to the radical Sextus Empiricus and beyond, to Parmenides and Zeno--"doubt" remains a constantly miscomprehended action and posture. Doubt is a state of the suspension of both belief and disbelief: many people assume that thinking has only two positions, positive and negative, and if you doubt something you are disputing its validity or positing the contradictory position. This is disputation, not doubt. Doubt per se questions the form or content of what has been asserted but it itself is a freeform state of wondering what the general parameters of the issue are and how it most rationally ought to be framed. Such particulars as most people are familiar with--position A or not-A, conservative or liberal, Christian or atheist, etc.--are never authoritative or exhaustive alternatives for a truly thinking and creative or radical mind (determined to go for fundamental principles, not their peripheral consequences or specific applications). They are "stock fallacies" or forced choices.
