Although I'm a Szaszian who doesn't think "psychological disorder" is a valid concept, I have known one person who was psychological diagnosed as dyslexic precisely for those reasons. It destroyed her life. I don't know whom to hate more, the pragmatists who taught her to seek selfhood in emotions terrified of thought, or the empirical psychologists who then crushed her self-esteem with a label, or her mother, who used the diagnosis to break the spine of her independence to further her own power (specifically by linking it to the Paul's original presentation of original sin in Romans)-lust, or her father, who did try to help her recover her soul, but through a one sided, frustrated demand for "standards" which to her looked like just another cruel axe of judgement coming to descend upon her.
She became a person of wonderful romanticism, with wonderfully, passionate ideas that went through terribly, wasteful epicycles to get anywhere because she simply could not think in language. She could handle calculus, but not arithmetic; she could compose music, but feared studying it, she could understand Heidegger on a single reading, but could not write coherent sentences. She became scared of putting thoughts in any public language, and performed most analytic tasks in her own private language which she then *translated* into English.
She became a person who simply did not have any ability to choose her actions because her entire experience of life was tacit. She had a vivid imagination and a tacitly powerful ability to reason, but she volitionally stopped reasoning as soon as she consciously identified what she was doing as such. And she feared any kind of conscious ordering of her life as the preparation for a damning torrent of condemnations... with the result of paralysis in achieving any passion as soon as it began to make sense.
It took her 12 years and the creation of a new self for her to regain her pride, and even now, her independence is only a simulacra of what it could have been. The damn progressive educators pretend to be rebels, but really they just exist in a divide-and-conquer symbiosis with conservative patriarchs. Half of the people are taught to bear any orders, despite any suffering, for fear of an enervating feeling, while the other half are taught to be terrified of logic and seek solace in snuggling up to power.
Forgive me if I speak angrily; she was my lover, for five years. She taught me much, including some things that her own miseducation had made easier than my own. But she will never completely recover from what they did to her.
