Yet the history of Greece affords the explanation and even the justification of the popular idea. The pagan who is in us all, tends ever to draw us downwards from sacramental and symbolic ways of thinking to the easier life of the body and the earth. On the one hand, for blood that is young and hot, the life of sense is overwhelming. On the other hand, for the weary toiler whose mind is untrained, the impression of the world is that of heavy clay. Each in his own way finds idealism difficult to retain. The spirituality of nature floats like a dream before the mind of poets, and is seen now and then in wistful glimpses by every one; but it needs some clearer and less elusive form, as well as some definite association with conscience, if it is to be defended against the pull of the green earth. It has been well said that, for the Greek, God was the view; but when the traveller goes forward into the view, he meets with many things which it is dangerous to identify with God. For the young spirit of the early times the temptation to earthliness was overwhelming. The world was fair, its gates were open, and its barriers all down. Men took from literature and from religion just as much of spirituality as they understood and as little as they desired, and the effect was swift and inevitable in that degeneration which reached its final form in the degraded sensuality of the later Roman Empire. The confusing element in all such inquiry lies in the fact that one can never get an unmixed paganism nor a perfect idealism. Just as the claims of body and spirit are in our daily life inextricably interwoven, so the Greek thought hung precariously between the two, and was always more or less at the mercy of the individual interpreter and of the relative strength of his tastes and passions. So we shall find it all through the course of these studies. It would be preposterous to deny some sort of idealism to almost any pagan who has ever lived. The contrast between pagan and idealist is largely a matter of proportion and preponderating tendency: yet the lines are clear enough to enable us to work with this distinction and to find it valuable and illuminating.
