The Thing § 165
However, the thingly character of the thing does not consist in its being a represented object, nor can it be defined in any way in terms of the objectness, the over-againstness, of the object.
The jug remains a vessel whether we represent it in our minds or not. As a vessel the jug stands on its own as self-supporting. But what does it mean to say that the container stands on its own? Does the vessel's self-support alone define the jug as a thing? Clearly the jug stands as a vessel only because it has been brought to a stand. This happened during, and happens by means of, a process of setting, of setting forth, namely, by producing the jug. The potter makes the earthen jug out of earth that he has specially chosen and prepared for it. The jug consists of that earth. By virtue of what the jug consists of, it too can stand on the earth, either immediately or through the mediation of table and bench. What exists by such producing is what stands on its own, is self-supporting. When we take the jug as a made vessel, then surely we are apprehending it—so it seems—as a thing and never as a mere object.
Or do we even now still take the jug as an object? Indeed. It is, to be sure, no longer considered only an object of a mere act of representation, but in return it is an object which a process of making has set up before and against us. Its self-support seems to mark the jug as a thing. But in truth we are thinking of this self-support in terms of the making process. Self-support is what the making aims at. But even so, the self-support is still thought of in terms of objectness, even though the over-againstness of what has been put forth is no longer grounded in mere representation, in the mere putting it before our minds. But from the objectness of the object, and from the product's self-support, there is no way that leads to the thingness of the thing.
What in the thing is thingly? What is the thing in itself? We shall not reach the thing in itself until our thinking has first reached the thing as a thing.
