Before Wittgenstein closes the door on philosophy, let us think of two concepts texting and being. Though texting is not yet considered therapeutic, Ludwig might have considered it therapeutical.
Since the beginning of time people marked items as a means of passing information to others, this included stone carving, indents in clay, knotted lengths of cord and scratching of plates of lead, copper and wood.
Texting derives from astronomical observations, the introduction of characters from nature, fire, water, animals of the earth and birds of flight, and the beginning of the Syllabic method of writing i.e., the use of characters to represent sound.
Just as today's software programs increase our texting bandwidth so to speak, so too did the leaves of plants and the bark of trees advance the use of writing. Egyptian papyrus bought the ancient libraries of Alexandria and Pergamum to life.
Papyrus became so popular a writing material with the ancient Egyptian hipsters that laws were introduced preventing it leaving its country of origin in the East. This caused a shortage of papyrus in the West which led to the birth of new writing materials: Vellum and Parchment (produced from animal skins). Saxons of the dark ages used the bark of the beech tree, called boc, from whence comes the word book.
Not looking up is what I see of people everywhere I look. While walking down the streets of Paris (in front of the Galleries Lafayette - I can't say "Lafayette" without thinking of the word Laugh, which then makes me feel right at home in this shopping center given we share the same namesake), I see people everywhere walking while not looking up. I weave in and out and dodge them like Frogger crossing motor vehicles, logs, crocodiles, and turtles to arrive home.
