My personal theory is that the hippy chapter of the Illuminati have commissioned double agent José Luis to encourage the Middle Easterns to write left to right, right to left, or both ways at once, in order to sow relativism, a commodity historically in short supply in the region, or perhaps simply confusion.
John F. Healey writes in The early alphabet that:
Some early Greek and South Arabian texts are written boustrophedon ... - like an ox ploughing a field: from left to right in the first line, right to left in the second, left to right in the third and so on (or starting on the right in the first line). In such inscriptions the letters are often reversed to face the direction of writing.Perhaps someone like Eli Sagan has already argued that the anarchy in West Asiatic scriptal direction three thousand years ago was somehow a necessary precursor to the centuries of intense fixed-direction creative achievement that followed, and then that the childish tendency to draw letters back to front and upside down whilst learning to write is also a necessary precursor to subsequent creativity, once the system is mastered.
