of the essay, Newman introduces foundational concepts that will be explored throughout the work. He outlines the different modes of holding propositions—categorical, conditional, and interrogative—and connects these to the mental acts of doubt, inference, and assent. He emphasizes the importance of apprehension in relation to assent, arguing that genuine assent involves an intelligent and concrete understanding of propositions, particularly in matters of faith and belief. Furthermore, Newman begins to classify different forms of assent, laying the groundwork for a deeper analysis of how various factors influence our acceptance of truths, especially in religious contexts.
