In my perspective this derives from the fact that "knowledge" itself is not some abstract, immaterial thing in the brain, but rather thinking and knowing works through the body and the practical application. Hence the saying "hands-on". Understanding something requires experiencing it, as experience (sensation) is inseparable from consciousness. (We call this phenomenological Emboiment, feel free to check it out!)

You cannot build an ideal society in theory as it will not be realisitic in practice, and you cannot explain reason and feel with words alone, but others need to walk the same experiential path as you did. But since you already figured it out you can help them walk it faster. Thats why we now learn in primary school what originally took a long time until some greek matematician worked it out.
