"Heaven cannot but be high. Earth cannot but be broad. The sun and moon cannot but revolve. All creation cannot but flourish. To do so is their TAO. But it is not from extensive study that this may be known, nor by dialectical skill that his may be made clear. The true sage will have none of these."

Among all the liberal arts, the first is logic, and specifically that part of logic which gives initial instruction about words. ... [T]he word "logic" has a broad meaning, and is not restricted exclusively to the science of argumentative reasoning. [It includes] Grammar [which] is "the science of speaking and writing correctly-the starting point of all liberal studies."
