 [74] Nor can we say that the soul apprehends external existing objects through its sensory feelings inasmuch as the feelings of the senses are similar to the external existing objects. For how will the intellect know whether the feelings of the senses are like the sense-objects, given that it does not itself come into contact with the external objects and that the senses make clear to it not the nature of these objects but their own feelings, as we deduced from the modes of suspension? [75] Just as someone who does not know Socrates but has looked at a picture of him does not know whether the picture is like Socrates, so the intellect, studying the feelings of the senses but not observing the external objects, will not know whether the feelings of the senses are like the external existing objects. Therefore it cannot rely on similarity to judge them.
