Los pensamientos sin contenido son vacíos; las intuiciones sin conceptos…¿también? Contenidos mentales y objetos reales en Kant y Hegel

For Kant, “thoughts without content are empty; intuitions without concepts are blind” (KrV, A51/B75). This formula was directed against the conception of concepts held by authors such as Wolff and Baumgarten, who regarded as empty only those concepts whose content is contradictory. According to these thinkers, concepts whose content is possible are not empty, since their content consists in the sum of the determinations that define that content as such. For Kant, by contrast, even concepts of possible contents are empty, since, taken as such, they do not yield knowledge of an actually existing object; for this, an empirical intuition grounded in perception is required. Hegel, for his part, disputes the claim that the content of empirical intuitions contains anything more than its own determinate content. But if both the content of concepts and that of empirical intuitions are merely possible, when and how does the mind come into contact with the real world? For the explanatory model proposed by Hegel, this apparent problem rests on a fallacious line of argument, namely, that if both concepts and empirical intuitions are empty, then the totality formed by the two cannot itself be anything but empty. On the contrary, for Hegel the reference of contents to the real world results from the coherent system that mediates all determinate contents among themselves; the way in which concepts and empirical intuitions acquire their reference to the world is precisely through this totality insofar as it singularizes itself within itself as a concrete, particular object.
