 we can only apprehend the infinite in the infinite itself…. For the first principle of our knowledge is that nothingness is not perceptible, whence if follows that, if we think of the infinite, it must exist. We also see that God is not a deceiver, because, knowing that He is infinitely perfect and that the infinite cannot lack any perfection, we clearly see that He does not want to beguile us…. (ibid., OC 2:372; LO 481–2)
