Augustine is often credited for upholding a theory of active perception, whereby our acquaintance with ordinary material objects and their properties cannot be explained by the causal efficaciousness of these objects. In a previous work, I attempted to connect this theory with the account of perception found in his treatise On the Trinity. Mark Kalderon has challenged this ‘reconciliationist’ reading, claiming that in this work Augustine admits to a strong causal role of the object in bringing about perceptual experiences. In (...) this paper I stand by my original reading, with one important qualification: the object is a cause in determining the content of the act of perception, but not of the perceptual act or the activity of the soul in general.
