this other valid form, no elephant is as small as a tomato can; this object is just the size of a tomato can; hence this object is not an elephant. Had some one told me to look out and see an elephant, my perception would unconsciously have taken one of these forms. The scarlet is recognized as such only as it is identified with a previous impression of scarlet. Here is our third surprise in psychology. Unless there were a priori idea, sense-perception could never begin. More, unless there were a priori idea, it could not begin. For there must be two recognitions before there can be a first new idea from sense-perception. The fourth surprise is that directly with the first activity of perception in the second figure of the syllogism is joined a second activity which takes place in the form of the first figure of the syllogism. As soon as I perceived the red object to be a piece of flannel, I at once reinforced my sense-perception by unlocking all my previous store of knowledge stored up under the category of red flannel. I unconsciously syllogized thus: 'All red flannel has threads of warp and woof and a rough texture, caused by the coarse fibres of wool curling up stiffly; this is a piece of red flannel; hence this will be found to have these properties.' The act of recognition is a subsumption of the object under a class by use of the second figure of the syllogism. "Now begins the syllogistic activity under the form of the third figure. There are a variety of attributes which I recognize by the activity of the perceiving mind in the form of the first figure, as it recognizes the general classes by the primary activity in the form of the second figure. These attributes are collected around the object as a centre of interest, and it is now the middle term. These give a new element of experience, thus: 'Major--this is a tin can; minor--it lies neglected in the garden; conclusion--tin cans get abandoned to neglect.' And so on, as to the use of the contents and the value of the can, running out into a long series of inferences." As we have now reached the seventh heaven of Concord philosophy, and know how to distinguish an old tin can from an elephant, let us rest in peace, to meditate and enjoy its serene delights. We have had the supreme satisfaction of listening to the modern Plato, the leader at Concord. The _Herald_ has informed us that on another day "the school listened with great satisfaction to Prof. Harris, who is constantly adding to the deep impression he has already made, and to the high opinion in which he is held as the most acute and profound thinker of the times, in his field."
