Reading the work of Susanne Cook-Greuter makes my mind mushy. As it should. If you're into deconstructing "reality", check out her article Comprehensive Language Awareness: A Definition Of The Phenomenon And A Review Of Its Treatment In The Postformal Adult Development Literature (click on Papers & Resources from her home page). An excerpt follows. I also highly recommend Nine Levels of Increasing Embrace.

Living in language we live in a split or permanently separated state. All our categorization schemes, theories, and mental frameworks are originally built on arbitrary, though functional distinctions. This holds from the primitive sensory distinctions of babyhood to the most elaborate adult theories of what is good, beautiful and just or scientifically valid, predictive, and replicable.

We analyze, categorize, and define the "elements" of experience in ways that reinforce the notion of their separateness and permanence and thus afford us a measure of stability and predictability. Through language, we collude with each other in perpetuating the illusion of the permanent object world including the notion of our own separate personal selves. What is more, such categorizing is inevitably linked to value judgments as a legacy of cultural conditioning. Valuing high, we may despise low, wanting to feel strong, we may repress our more vulnerable feelings; fearing death, we may deny it. By considering part of our experience as undesirable, we get attached to the "desirable" side of the dichotomy. To become conscious of how language is intrinsically evaluating experience is a first step towards unlearning the habitual judging response.
