Conceptualizing thought and communication as either artificial or natural attributes or removes intention from its effect. The term “natural” finds its definition in separateness from human events—in that it is not produced, altered, or derived from our machinations. Thought, in this way, could be either artificial or natural—the lynchpin in that difference being the intent to think. My intent to answer this prompt categorizes the thoughts going into it as artificial, but their drifting to the cheeseburger stowed in the fridge, arguably natural as my mind drifts to it without approval.
Communication, within these guidelines, will almost always be artificial, as there is almost always an intent to communicate. Although one could feasibly argue citing hypnosis, sleep-talking, or moments of heightened emotional state as non-voluntary forms of communication. These loopholes, however, are sewn shut when words hit the paper.
The utility of thinking communication, particularly writing, as pure artifice, removes the possibility of supposedly inherent truths that stifle or stagnate arguments or positions. And this is a good thing for, once an idea crescendos to truth, it starts to decay—as all creations do when the building stops.
