While, however, the Dogmatics are conceited enough to think 90 that they should be preferred to other men in the judgement of things, we know that their claim is absurd, for they themselves form a part of the disagreement; and if they give themselves preference in this way in the judgment of phenomena, they beg the question before they begin the judgment, as they trust the judgment to themselves. Nevertheless, in order that we should 91 reach the result of the suspension of judgment by limiting the argument to one man, one who for example they deem to be wise, let us take up the third Trope. This is the one that is based upon differences in perception. That the perceptions 92 differ from each other is evident. For example, paintings seem to have hollows and prominences to the sense of sight, but not to the sense of touch, and honey to the tongue of some people appears pleasant, but unpleasant to the eyes; therefore it is impossible to say whether it is really pleasant or unpleasant. In regard to myrrh it is the same, for it delights the sense of smell, but disgusts the sense of taste. Also in regard to 93 euphorbium, since it is harmful to the eyes and harmless to all the rest of the body, we are not able to say whether it is really harmless to bodies or not, as far as its own nature is concerned. Rain-water, too, is useful to the eyes, but it makes the trachea and the lungs rough, just as oil does, although it soothes the skin; and the sea-torpedo placed on the extremities makes them numb, but is harmless when placed on the rest of the body. Wherefore we cannot say what each of these things is by nature. It is possible only to say how it appears each time. We 94 could cite more examples than these, but in order not to spend too long in laying out the plan of this book we shall simply say the following: Each of the phenomena perceived by us seems to present itself in many forms, as the apple, smooth, fragrant, sweet, yellow. Now it is not known whether it has in reality only those qualities which appear to us, or if it has only one quality, but appears different on account of the different constitution of the sense organs, or if it has more qualities than appear to us, but some of them do not affect us. That it has only one quality might be concluded from what we 95 have said about the food distributed in bodies, and the water distributed in trees, and the breath in the flute and syrinx, and in similar instruments; for it is possible that the apple also has only one quality, but appears different on account of the difference in the sense organs by which it is perceived. On 96 the other hand, that the apple has more qualities than those that appear to us, can be argued in this way: Let us imagine someone born with the sense of touch, of smell, and of taste, but neither hearing nor seeing. He will then assume that neither anything visible nor anything audible exists at all, but only
