If by “infused knowledge” you mean natural (secular) or supernatural (spiritual) knowledge miraculously conferred by God, then it is often the case that such knowledge is partial. For example, knowledge of spiritual things does not fully comprehend God, for example, but only provides a glimpse of the fathomless mystery of God. Nonetheless, infused knowledge can seem to be “absolute” compared to knowledge obtained naturally, i.e., through long years of study and reflection, such as when St. Thomas Aquinas, after a profound spiritual experience, referred to all of his previous knowledge as mere “straw”.
