Answerable to sense, or arbitrary, 26. With their parts, and colours, 27. And are the materials of wit and ingenuity, 28. Of these acts, which [are] proper to mankind, 29. Upon perception, follow the several sorts of volition or affection, 30. Their various mixture, 31. And symptoms, 32. From hence, habits, 33. And passions, 34, 35. The necessity of an incorporeal principle, demonstrated from the organ of phancy, 36, 37, 38. And from its several acts, 39, 40, 41. The office of phancy, in generation, 42. In the use of corporeal habits, 43. And of mental, 44, 45, 46.
The intellect has its proper objects and acts, 1. Sense and phancy have nothing to do with the definition of the Deity, 2. Nor of anything else, 3, 4, 5. Nor with universals, 6. The forming of which [is] peculiar to the intellectual mind, 7. Intellection defined, 8. Its acts, 9. The first, namely, perception, has two modes, 10. The first, dubitation, 11. Attended with disquisition and collation, 12, 13. The other, invention: improperly, or properly so called, 14, 15, 16. Attained either by sense, 17. Or by first theorems, 18. Or by consequence, 19. All knowledge, truly so called, [is] of equal certitude, 20. To suppose the incertitude of any, but that of sense and mathematics, [is] absurd, 21. Yet demonstration and comprehension [are] two things; showed by divers instances, 22, 23, 24, 25. Next to perception, [is] volition, 26. Its modes, 27. And concomitancy with the understanding, 28, 29, 30.
Truth, the object of the understanding, 1, 2. The several sorts of truth, 3. Theoremic truth, twofold, 4. Positive truth, the chief ground of science; which consists in defining the essences of things, 5, 6. The difference between genus and generality, 7. Definitions of things simple, or sensible, [are] the most perfect, 8. As of quantity; which we may consider abstractly, 9. In geometry, we must, 10. And of its relations; namely, equality, 11. Proportionality, 12. And commensurability, 13. As also, of regular figures, 14. And their relations, namely, similitude, 15. And coexistence, 16. The definitions of all other things [are] unattainable; proved by instances, 17, 18, 19. Definitions so called are no more than certain titles or marks to know them by, 20, 21, 22. Nor are the ideas we have of figure and quantity absolutely perfect; proved by instances, 23, 24, &c. to 30. Much less [is] that which we have of the Deity, 31. Yet we are not to stay, with the schools, upon mere titles, but to go as far as we can, 32.
