问答题Practice 4 In like manner we cannot refer the whole phenomena of the Renaissance to any one cause or circumstance, or limit them within the field of any one department of human knowledge. If we ask the students of art what they mean by the Renaissance, they will reply that it was the revolution effected in architecture, painting, and sculpture by the recovery of antique monuments. Students of literature, philosophy, and theology see in the Renaissance that discovery of manuscripts, that passion for antiquity, that progress in philology and criticism, which led to a correct knowledge of the classics, to a fresh taste in poetry, to new systems of thought, to more accurate analysis, and finally to the Lutheran schism and the emancipation of the conscience. Men of science will discourse about the discovery of the solar system by Copernicus and Galileo, the anatomy of Vesalius, and Harvey’s theory of the circulation of the blood. The origination of a truly scientific method is the point which interests them most in the Renaissance. The political historian, again, has his own answer to the question. The externalities of Europe, the growth of monarchy, the limitation of the ecclesiastical authority and the erection of the Papacy into an Italian kingdom, and in the last place the gradual emergence of that sense of popular freedom which exploded in the Revolution.
