We now proceed to the latter clause of our general proposition. And here it may be asked, on what ground we assume one intuitive universal Principle as the true source of all those emotions which have just been discussed. To this we reply, On the ground of their common agreement. As we shall here use the words _effect_ and _emotion_ as convertible terms, we wish it to be understood, that, when we apply the epithet _common_ or _same_ to _effect_, we do so only in relation to _kind_, and for the sake of brevity, instead of saying the same _class_ of effects; implying also in the word _kind_ the existence of many degrees, but no other difference. For instance, if a beautiful flower and a noble act shall be found to excite a kindred emotion, however slight from the one or deep from the other, they come in effect under the same category. And this we are forced to admit, however heterogeneous, since a common ground is necessarily predicated of a common result. How else, for instance, can we account for a scene in nature, a bird, an animal, a human form, affecting us each in a similar way? There is certainly no similitude in the objects that compose a landscape, and the form of an animal and man; they have no resemblance either in shape, or texture, or color, in roughness, smoothness, or any other known quality; while their several effects are so near akin, that we do not stop to measure even the wide degrees by which they are marked, but class them in a breath by some common term. It is very plain that this singular property of assimilating to one what is so widely unlike cannot proceed from any similar conformation, or quality, or attribute of mere being, that is, of any thing essential to distinctive existence. There must needs, then, be some common ground for their common effect. For if they agree not in themselves one with the other, it follows of necessity that the ground of their agreement must be in relation to something within our own minds, since only _there_ is this common effect known as a fact. We are now brought to the important question, _Where_ and _what_ is this reconciling ground? Certainly not in sensation, for that could only reflect their distinctive differences. Neither can it be in the reflective faculties, since the effect in question, being co-instantaneous, is wholly independent of any process of reasoning; for we do not feel it because we understand, but only because we are conscious of its presence. Nay, it is because we neither do nor can understand it, being therefore a matter aloof from all the powers of reasoning, that its character is such as has been asserted, and, as such, universal. Where, then, shall we search for this mysterious ground but in the mind, since only there, as before observed, is this common effect known as a fact? and where in the mind but in some inherent Principle, which is both intuitive and universal, since, in a greater or less degree, all men feel it _without knowing why?_
