Wittgenstein considered the unstated ethical dimension of the Tractatus its essential part.

Evidence

My work [the manuscript of the Tractatus] consists of two parts: the one presented here plus all that I have not written. And it is precisely the second part that is the important one. My book draws limits to the sphere of the ethical from the inside as it were, and I am convinced that this is the ONLY rigorous way of drawing those limits. — Philip Chase Bobbitt, Reflections Inspired by My Critics, 134
