I disagree. Humans have an innate curiosity, yes. Humans have a highly developed ability to see patterns and to think about them, whether the patterns they see actually exist or not, and whether the rational patterns they derive from perception hold water or not. Humans are also very prone to taking refuge in the comfort of habit, and calling that comfort "truth" - whether that comfort is true, or not.
If human beings detect a pattern, I am persuaded that the pattern must exist; and if it does, it has meaning. Most of the serious human beings I know do not "hallucinate" their way through life. So if there is a pattern, it must needs to be understood. By thinking human beings.
Of course I am not speaking of human beings who find comfort in "habit." I am speaking of rational people, who care very much about understanding the universe of which they are parts and participants. We humans have a great stake in getting such questions "right," for both personal and social reasons. That's where the subject of morality comes into play; for morality is ever about the order of the person (i.e., the order of the soul), and from there to the order of the society in which the person lives.
It may come as a surprise to you, but arguably, Plato was the very first explicitly political philosopher, creating the science of politics in the process. His great insight about political reality is that every "polis," or political order or "State," is nothing more than the aggregation of the most common expression of the personal soul of the people comprising the society, writ large. If the majority of souls comprising the Polis (the political State) are disordered, then the Polis itself will be disordered. And no law, no legislation can cure what would follow next.
Plato insisted that the Cosmos itself is "ordered." Which means it is not "accidental." Indeed, the Greek word kosmos means "order." He also thought that man was the "microkosmos" -- an image of the entire universe in himself, like a "child" of a Mandelbrot set if I might suggest that analogy. In other words, man recapitulates in himself all the orders of being, from the inorganic to the divine.
Notice, dear King, that we humans are not the ones who set up the categories of judgment of such questions. We did not invent logic, nor reason. Human curiosity is the very thing that keeps humans in step with the world in which they live. And so I imagine curiosity is a divine gift to humans. Along with reason and logic.
Well, my two-cents worth anyway. Thank you dear for the conversation.
