True Progressivism

Yesterday I read G. K. Chesterton’s Heretics for the first time and came across a passage on progress:

The case of the general talk of “progress” is, indeed, an extreme one. As enunciated today, “progress” is simply a comparative of which we have not settled the superlative. We meet every ideal of religion, patriotism, beauty, or brute pleasure with the alternative ideal of progress—that is to say, we meet every proposal of getting something that we know about, with an alternative proposal of getting a great deal more of nobody knows what. Progress, properly understood, has, indeed, a most dignified and legitimate meaning. But as used in opposition to precise moral ideals, it is ludicrous. So far from it being the truth that the ideal of progress is to be set against that of ethical or religious finality, the reverse is the truth.

Nobody has any business to use the word “progress” unless he has a definite creed and a cast-iron code of morals. Nobody can be progressive without being doctrinal; I might almost say that nobody can be progressive without being infallible — at any rate, without believing in some infallibility. For progress by its very name indicates a direction; and the moment we are in the least doubtful about the direction, we become in the same degree doubtful about the progress . . . . I do not, therefore, say that the word “progress” is unmeaning; I say it is unmeaning without the previous definition of a moral doctrine, and that it can only be applied to groups of persons who hold that doctrine in common. Progress is not an illegitimate word, but it is logically evident that it is illegitimate for us. It is a sacred word, a word which could only rightly be used by rigid believers and in the ages of faith.
