In Aquinas, the senses are widely construed as “gatekeepers” restricting the possible content of our embodied intellectual thought. But if this is true, how can Aquinas justify his extensive theorizing about incorporeal substances, and how can he account for human experiential self-awareness? This paper argues that, for Aquinas, the scope of our embodied experience is not limited to objects of sense, but extends to our intellects and everything ontologically “below” them; we can and do conceptualize something incorporeal—the intellectual soul—as it (...) is in itself and not merely by comparison to bodies; this concept of ‘incorporeality’ is precisely a concept of ‘intellectuality.’ The restrictions embodied human intellects encounter in attempting to know entities “above” us arise less from their incorporeality than from a fundamental mismatch between our attempts to conceptualize them in terms of what they have in common with us, and their simplicity.
