in some places bark, in other places branches, and in other places fruit, perhaps a fig or a pomegranate, or something else; just as the breath of the musician, one and the same 54 when blown into the flute, becomes sometimes a high tone and sometimes a low one, and the same pressure of the hand upon the lyre sometimes causes a deep tone and sometimes a high tone, so it is natural to suppose that external objects are regarded differently according to the different constitution of the animals which perceive them.  We may see this more clearly in 55 the things that are sought for and avoided by animals.  For example, myrrh appears very agreeable to men and intolerable to beetles and bees.  Oil also, which is useful to men, destroys wasps and bees if sprinkled on them; and sea-water, while it is unpleasant and poisonous to men if they drink it, is most agreeable and sweet to fishes.  Swine also prefer to wash in vile filth rather than in pure clean water.  Furthermore, some 56 animals eat grass and some eat herbs; some live in the woods, others eat seeds; some are carnivorous, and others lactivorous; some enjoy putrified food, and others fresh food; some raw food and others that which is prepared by cooking; and in general that which is agreeable to some is disagreeable and fatal to others, and should be avoided by them.  Thus hemlock makes the 57 quail fat, and henbane the hogs, and these, as it is known, enjoy eating lizards; deer also eat poisonous animals, and swallows, the cantharidae.  Moreover, ants and flying ants, when swallowed by men, cause discomfort and colic; but the bear, on the contrary, whatever sickness he may have, becomes stronger by devouring them.  The viper is benumbed if one twig of the oak 58 touches it, as is also the bat by a leaf of the plane-tree.  The elephant flees before the ram, and the lion before the cock, and seals from the rattling of beans that are being pounded, and the tiger from the sound of the drum.  Many other examples could be given, but that we may not seem to dwell longer than is necessary on this subject, we conclude by saying that since the same things are pleasant to some and unpleasant to others, and the pleasure and displeasure depend on the ideas, it must be that different animals have different ideas of objects.  And since the same things appear different according to the 59 difference in the animals, it will be possible for us to say how the external object appears to us, but as to how it is in reality we shall suspend our judgment.  For we cannot ourselves judge between our own ideas and those of other animals, being ourselves involved in the difference, and therefore much more in need of being judged than being ourselves able to judge.  And furthermore, we cannot give the preference to our own mental 60 representations over those of other animals, either without evidence or with evidence, for besides the fact that perhaps there is no evidence, as we shall show, the evidence
