.H 4 The need for interpretation. .PP Consider the hypothesis that the rationalization of experience in exposition and argument is invariably constructive and beneficial, that it extends the acuity of the senses, that it enhances the ability to act, that it provides control and correction to an otherwise opaque existence, that it constitutes the single most important medium of communication, and the only true community of thought, and that, in general, it adds a new and different dimension to our lives. .PP To be sure, rationalization can be all this, it is plausible to argue that rationalization fulfills all these functions, but less felicitous aspects of rationalization ought not to be denied. Rationalization can also create misleading and deceptive conceptual artifacts; it can generate fantasies and myths that absorb and dissipate man's intellectual and emotional resources, concealing his mistakes and short-comings, fictions by means of which he puts himself into the best possible light, and screens with which he conceals his errors from himself and from all others whom he is able to persuade to believe him. .PP I know of no device, in any given instance, to distinguish the alternnative, to determine to what extent a given rationalization fulfills a beneficial, and to what extent it has a detrimental function. In every instance, I believe, it will be necessary to look to the consequences of the conceptual invention to assess its value; and where the conceptualization presents itself as it were with built-in value, proclaiming and assertings is validity on its face, there one must be tough and critical, and disregard what the argument claims in its own behalf and ignore its claim to truth; and test it against experience, to determine how well it will hold up. .PP The foregoing considerations suggest that criticism and interpretation will be the task of every reader of any given text, and this one is no exception. Notice that the process of interpretation will function somewhat in the manner of a filtering or converting device; inasmuch as that it is when a reader takes a text seriously, thinks and worries about it, when, in order to fulfill the task of interpretation, the reader reads passionately, which is to say that he cares about what he reads and that its truth matters to him: then the process of interpretation will serve not so much as a filter to eliminate and exclude what appears meaningless or incongruous or incorrect; but the process of interpretation will supplement the text and thereby correct that error. That which was meaningless becomes meaningful in its meaninglessness when it is interpreted. The process of interpretation corrects the error which it detects.
