There is a persistent intuition running from the earliest to the most recent works on the topic, that obligatory control (OC) complements fall into two distinct types. In this study I recast this intuition in terms of the semantic distinction between attitude and nonattitude complements. I argue that the latter establish control by simple predication ("predicative control") but the former establish it by variable binding, where the bound variable is a projected coordinate of the embedded context of evaluation ("logophoric control"). I offer an explicit syntax-semantics analysis of the two types, utilizing the idea that logophoric control structures are constructed as a second tier above predicative control structures. In both, PRO figures as a minimal, featureless pronoun, which functions as a -abstractor upon movement. The analysis derives the obligatory de se reading of OC PRO as a special kind of de re attitude, without ascribing any inherent feature to PRO (a minimal pronoun). At the same time, it provides a principled explanation, based on feature transmission, for the agreement properties of PRO, which are stipulated on competing semantic accounts (the property theory and the indexical shift theory of OC). Importantly, it is capable of deriving a striking universal asymmetry between OC in attitude and non-attitude contexts: the fact that agreement on the embedded verb blocks the former but not the latter. This is handled by reference to the differential agreement properties of predication and variable binding. Further contrasts between the two types of OC follow, some of which unnoticed before, such as the visibility of implicit controllers and the [±human] value of PRO. I dedicate this work to all those who spend years and decades working on the same topic and never stop marveling at the most elementary puzzles that lured them in the first place.
