One thing some may not remember is that writing by hand is how ideas are created through our whole body: it's our whole body transmitting an idea and this idea leaves the realm of the mind. Ideas only take form by means of expression, like writing using a code. When we just read and think, we're using reason, and we are not expressing our self, because the information is only in the realm of mind. Writing is a form of expression and any human form of expression is art per se.
Art is outside the realm of the mind. Art is art; it is what it is, regardless what our mind think of it, our interpretation of it. Since we're mindful beings, we do not realize the importance of selfexpression. Mind is a sense, just like smell, vision...
By writing by hand, our whole body expresses himself as well as our spirit. Our spirit is not our mind. To give voice to our whole senses, we just need an instrument, a pencil, for example. Our body, arms, fingers, nails, eyes, ears, spirit and mind are going to be part of something together, selfexpression, which can be accomplished with the alphabet. When we just think something over, we're trapped in the realm of mind, just one sense. Letting people read our thoughts and evaluate them gives us the chance to understand more about our self, about who we are. Discovering something can be done then through writing.
It's another realm, it's the realm of art, when our self encounters a way for expression. We can use someone else writtings to evaluate alzheimmer disease, for example, and it's obivous why.
For example, a typewriter machine dictates its own rhythm, which is fast, and it's not the speed of the human natural way of writing. See for example Friedrich Nietzsche's writings done by typewriters and the ones by hand. Changing the instrument alters the way we express ourselves. Writing using a keyboard and a monitor/screen doesnt allow us to have a good rythm, because we can write very fast using the distribution of letters of the keyboard, and our thoughts may get shuffled because we write so fast, and we do not have the patience to write slowly, because the keyboard and the computer are machines that were designed for speed purposes. Wrinting by pencil, feathers, anything that allows free hand movement, is an experience through which you reveal a part of your self, just like using any substance may revealsomething, because it triggers an experience. Writing by hand is feeling an experience and it demands years of practice but the reward is along the path and not at the end.
