Page 56-78 Subjects embraced by the study of the Cosmos or of physical cosmography. Separation of other kindred studies -- p. 56-62. The uranological portion of the Cosmos is more simple than the telluric; the impossibility of ascertaining the diversity of matter simplifies the study of the mechanism of the heavens. Origin of the word 'Cosmos', its signification of adornment and order of the universe. The 'existing' can not be absolutely separated in our contemplation of nature from the 'future'. History of the world and description of the world -- p. 26-73. Attempts to embrace the multiplicity of the phenomena of the Cosmos in the unity of thought and under the form of a purely rational combination. Natural philosophy, which preceded all exact observation in antiquity, is a natural, but not unfrequently ill-directed, effort of reason. Two forms of abstraction rule in the whole mass of knowledge, viz.: the 'quantitative', relative determinations according to number and magnitude, and 'qualitative', material characters. Means of submitting phenomena to calculation. Atoms, mechanical methods of construction. Figurative representations; mythical conception of imponderable matters, and the peculiar vital forces in every organism. That which is attained by observation and experiment (calling forth phenomena) leads, by analogy and induction, to a knowledge of 'empirical laws'; their gradual simplification and generalization. Arrangement of the facts discovered in accordance with leading ideas. The treasure of empirical contemplation, collected through ages, is in no danger of experiencing any hostile agency from philosophy -- p. 73-78.
