resmts of observation, which is so much the more tliilicult to 

 hake, as it denies the validity of the facts by which it may 

 be refuted. This empiricism, the melancholy heritage trans- 

 mitted to us from former times, invariably contends for the 

 truth of its axioms with the arrogance of a narrow-minded 

 pirit. Physical philosophy, on the other hand, when based 

 upon science, doubts because it seeks to investigate, distin- 

 guishes between that which is certain and that which is mere- 

 xihle. and strives incessantly to perfect theory by ex- 

 ton ling the circle of observation. 



This assemblage of imperfect dogmas, bequeathed by one 

 age to another this physical philosophy, which is composed 

 of popular prejudices is not only injurious because it perpet- 

 aates error with the obstinacy engendered by the evidence of 

 ill-observed facts, but also because it hinders the mind from 

 attaining to higher views of nature. Instead of seeking to 

 discover the mean or medium point, around which oscillate, 

 in apparent independence of forces, all the phenomena of the 

 external world, this system delights in multiplying exceptions 

 to the law, and seeks, amid phenomena and in organic forms, 

 for something beyond the marvel of a regular succession, and 

 an internal and progressive development. Ever inclined to 

 believe that the order of nature is disturbed, it refuses to rec 

 ognize in the present any analogy with the past, and, guided 

 by its own varying hypotheses, seeks at hazard, either in the 

 interior of the globe or in the regions of space, for the cause 

 of these pretended perturbations. 



It is the special object of the present work to combat those 

 errors which derive their source from a vicious empiricism and 

 from imperfect inductions. The higher enjoyments yielded by 

 the study of nature depend upon the correctness and the depth 

 of our views, and upon the extent of the subjects that may be 

 comprehend^ 1 in a single glance. Increased mental cultiva- 

 .13 given rise, in all classes of society, to an increased de- 

 sire of embellishing life by augmenting the mass of ideas, and 

 by multiplying means for their generalization ; and this sen- 

 innent fully refutes the vague accusations advanced against 

 the age in which we live, showing that other interests, be- 

 ides the material wants of life, occupy the rninds of men. 



It is almost with reluctance that I am about to speak of a 



iciitiment, which apneus to arise from narrow-minded views, 



or from a certain weak and morbid sentimcnta'ity I allude 



fear entertained by some persons, that r ature may by 



degrees lose a portion of the charm and magic cf her power.
