Systematic, interdisciplinary and multidisciplinary study on the issue of blindness (as a Human and Social Science), in a theoretical-empirical and scientific context, whose first term, understood as the genesis of terminology and conceptuality, emerged in the 19th century, was Tiflophilia ( attachment/dedication to the blind person's cause/problem).   

​

Typhlology is a vast epistemic field intertwined with diverse scientific affinities, which deals with perceptive, somatosensory and kinesthetic haptic research and development, echolocation and locomotion (orientation and mobility), multisensory and ergoeducational, cognitive and sociocognitive, infocommunicational and sociocommunicational, biopsychosocial and human of blind people, thus seeking to maximize diversity, in the sphere of the ecology of knowledge and well-being, and, in this diversity, promoting equity in quality and opportunities for all, demonstrably demonstrating the potential and skills of blind people, in analogy with those of visually impaired people, in the social, ethical and civic world, in which we are all obliged, by duty and citizenship, to contribute to their development and progress.
