At the outset, truth was defined as the "correspondence" or "agreement" of an idea with its object. But we have seen that correspondence or agreement with an object means the completion and determination of the idea itself, and since the idea is here a specific "plan of action," it would seem that the "true" idea would be the one that can complete itself by stimulating a satisfying activity. The false idea would be one that cannot complete itself in a satisfying activity, such as singing in tune, constructing a mathematical equation, etc., and just this solution is very clearly expounded by our author. In the case of mathematical inquiry,
In just so far as we pause satisfied we observe that there "is no other" mathematical fact to be sought in the direction of the particular inquiry in hand. Satisfaction of purpose by means of presented fact and such determinate satisfaction as sends us to no other experience for further light and fulfillment, precisely this outcome is itself the Other that is sought when we begin our inquiry.[194]
So "when other facts of experience are sought," if I watch for stars or for a chemical precipitate, or for a turn in the stock market, or in the sickness of a friend, my ideas are true when they are satisfied with "the presented facts." Again,
It follows that the finally determinate form of the object of any finite idea is that form which the idea itself would assume whenever it became individuated, or in other words, became a completely determined idea, an idea or will fulfilled by a wholly adequate empirical content, for which no other content need be substituted or from the point of view of the satisfied idea, could be substituted.[195]
In such passages as these it seems clear that the test of the truth of an idea is its power to bring us to the point where we "pause satisfied," where "no other content need be substituted," etc. Nor in such passages does there seem to be any doubt of reaching satisfaction in particular cases. Here, it appears, we may sing in tune, we may get the desired precipitate, and possibly even interpret the stock market correctly. Of course, the discord, the hunger, the loss, will come again; but so will new ideas, new truths. "Man thinks in order to get control of his world and thereby of himself."[196] Then the control actually gained must measure the value, the truth of his thought. Do you wish to sing in tune, "then your musical ideas are false if they lead you to strike what are then called false notes."[197]
It should also be noticed that here this desired determination does not consist in a further determination of the mere idea as such. It is found in "the presented fact," in the immediate activity of singing, of getting precipitates, etc. As has already been pointed out, it is only by using the term "idea" for both the purpose and the fulfilling act of singing that this "pause of satisfaction" can be ascribed to the further determination of the idea. As such, as also before remarked, the sort of determination that the idea here gets means its termination, its disappearance in the immediate experiences of singing, etc., to which it leads. The "indefinite restlessness" of hunger and cold would scarcely be satisfied by getting more determinate and specific ideas only of food and shelter. The satisfaction comes when the ideas are "realized," when the "plans" are swallowed up in fulfilment.
But in all this nothing has been said about "the certain absolute system of ideas," nor does there appear to be here any demand for it. To be sure, in the passages just considered, experience has been found to become "fragmentary," but it has also been found capable of healing, of wholing itself, not of course into any "final whole," but into the unity of "satisfaction" as regards "the particular inquiry in hand." There is of course failure as well, but this also is not final. It means simply that we must look farther for the "pause of satisfaction," that we must construct another idea, another "plan of action."
But, after having shown that the idea as a plan of action may lead to satisfaction in the particular case, and that its success or failure so to do is one measure of its truth or falsity, we are now suddenly aroused to the fact that after all thought does not lead us to the completed "absolute system of ideas," to a final stage of eternal unbroken satisfaction.
But never in our human process of experience do we reach that determination. It is for us the object of love and of hope, of desire and of will, of faith and of work, but never of present finding.[198]
If at this point one asks: Whence this absolute system of ideas? Why have we to reckon with it at all? there appears to be little that is satisfying. Indeed, it seems difficult to get rid of the impression that this "certain absolute system of ideas" is on our hands as a philosophical heirloom from the time of Plato, so hallowed by time and so established by centuries of acceptance that we have ceased to ask for its credentials. To ground it in the "essentially fragmentary character of human experience" appears to be a petitio, for experience does not appear "essentially fragmentary" in this sense until after the absolute system has been posited.
