It is certain that these doctrines only worked upon Italy through Germany, and this not till the power of Spain was sufficiently great to root them out without difficulty, partly by itself and partly by means of the Papacy, and its instruments.105 Nevertheless, in the earlier religious movements of Italy, from the Mystics of the thirteenth century down to Savonarola, there was a large amount of positive religious doctrine which, like the very definite Christianity of the Huguenots, failed to achieve success only because circumstances were against it. Mighty events like the Reformation elude, as respects their details, their outbreak and their development, the deductions of the philosophers, however clearly the necessity of them as a whole may be demonstrated. The movements of the human spirit, its sudden flashes, its expansions and its pauses, must for ever remain a mystery to our eyes, since we can but know this or that of the forces at work in it, never all of them together.
The feeling of the upper and middle classes in Italy with regard to the Church at the time when the Renaissance culminated, was compounded of deep and contemptuous aversion, of acquiescence in the outward ecclesiastical customs which entered into daily life, and of a sense of dependence on sacraments and ceremonies. The great personal influence of religious preachers may be added as a fact characteristic of Italy.
