128. The worldly and corporeal man says in his heart, If I am not instructed concerning the faith, and everything relating to it, by means of the things of sense, so that I may see, or by means of those of the memory [scientifica], so that I may understand, I will not believe; and he confirms himself in this by the consideration that natural things cannot be contrary to spiritual. Thus he is desirous of being instructed from things of sense in what is celestial and Divine, which is as impossible as it is for a camel to go through the eye of a needle; for the more he desires to grow wise by such means, the more he blinds himself, till at length he believes nothing, not even that there is anything spiritual, or that there is eternal life. This comes from the principle which he assumes. And this is to "eat of the tree of the knowledge of good and evil" of which the more anyone eats, the more dead he becomes. But he who would be wise from the Lord, and not from the world, says in his heart that the Lord must be believed, that is, the things which the Lord has spoken in the Word, because they are truths; and according to this principle he regulates his thoughts. He confirms himself by things of reason, of knowledge, of the senses, and of nature [per rationalia, scientifica, sensualia et naturalia], and those which are not confirmatory he casts aside.
