The Speech of Monkeys

To reason is to think methodically and to judge from attending facts. When a monkey examines the situation and acts in accordance with the facts, doing a certain thing with the evident purpose of accomplishing a certain end, in what respect is this not reason? When a monkey remembers a thing which has passed and anticipates a thing which is to come; when he has learned a thing by experience which he avoids through memory and the apprehension of its recurrence, is it instinct that guides his conduct? When a monkey shows clearly by his actions that he is aware of the relation between cause and effect, and acts in accordance therewith, is it instinct or reason that guides him? If there be a point in the order of Nature where reason became an acquired faculty, it is somewhere far below the plane occupied by monkeys. Their power of reasoning is far inferior to that of man, but not more so than their power of thinking and expression; but a faculty does not lose its identity by reason of its feebleness. When the same causes under the same conditions prompt man and ape alike to do the same act in the same way, looking forward to the same results, I cannot understand why the motive of the one should be called reason, and that of the other called instinct. Scholars have tried so hard to keep the peace between theology and themselves, that they have explained things in accordance with accepted belief in order that they might not incur the charge of heresy. To this end they have reconciled the two extremes by ignoring the means, and making a distinction without a difference on which to found it.
