In the first part of the paper, I argue that explicating systems which fall under the simple theory of types are limited in explicating our conceptual scheme. Such limitation is avoided if one utilizes, instead, a ramified type theory, especially the one developed by Pavel Tichý. In the third part of the paper, I explain the role of so-called constructions and derivation systems within such a framework, elucidating how deduction demonstrates properties of objects.
