The moral judgment formed on the movement seen in the whole period must vary with the phase of it viewed. The attack is not, like those of the early unbelievers, a struggle with which the sympathies of Christians cannot be enlisted. The darker aspects of it partake indeed of the same character; but it embodies a better element, a nobler form of movement, tainted perhaps with doubt, but not with disbelief; viz. the attempt of the human mind to assert its rights in philosophy, theology, and politics; and as the epoch closes, the great truth has made itself felt in the world as the result of the contest, that Christianity is supreme only within its own sphere, which it is the problem of religious philosophy to discover; that freedom of inquiry is to be used outside the boundary, but that speculation must expire in adoration within it. ------------------------------------- A new crisis may be considered to commence in the fifteenth century, in consequence of the introduction of fresh influences through the classical revival. Yet as the two periods are connected in time, the transition is not sudden: the old influences gradually vanish away; the new ones had been slowly preparing before they became distinctly evident. The intellectual and social activity of the past period had been the means of educating the mind of Europe for the reception of the new forces which were now beginning to operate.(300) The fifteenth century was a remarkable period for Europe, and preeminently for Italy. During several ages Italy had grown great by means of commerce and religion. The crusades, which had impoverished the rest of Europe, had enriched her; and the subjugation of the nations to the court of Rome had made her the treasury of Europe. Material wealth permitted the encouragement of the study of literature, which relations of commerce or of conquest with the Greek empire had been the means of reviving. Manuscripts were collected, and the remains of monuments of classic art were studied. The love of antiquity gave perfection to art, and influenced literature. The work which centuries had slowly prepared now came to perfection. The scholastic philosophy declined; the sources of ecclesiastical education and of the existing religion were weakened; and by the close of the fifteenth century the tone of the age was in all respects changed. The devotion which had expressed itself in the great Gothic works of devotion of early ages was expiring, at least in Italy, and art itself gradually became secular, and expressed ideas more earthly.
