PHYSICS AND FAITH.* 
Our knowledge concerning the properties 
of and changes in matter is gained in the 
first place through our bodily senses, and 
secondly through the intellect; the pri- 
mary concepts thus acquired are confirmed, 
modified and enlarged by operations of the 
imagination and of the reason. The five 
senses with which we are endowed are of 
very unequal value in the acquisition of 
knowledge of natural objects; smelling, 
tasting and hearing make but small and 
unimportant contributions compared with 
those communicated by the senses of sight 
and of feeling. 
An intelligent being, having only the single 
sense of feeling, would nevertheless be able 
to handle a large number of objects within 
his reach and to study their properties ; he 
would early distinguish between matter at 
rest and matter in motion ; he would notice 
the properties of inertia and of weight; he 
would perceive in his person the effects of 
heat and of cold, of dryness and of moisture ; 
he would become acquainted with the shape 
of bodies of moderate size and with their 
superficial properties, such as smoothness 
or roughness, softness or hardness; he 
might, if he made sagacious use of his one 
power, recognize the distinction between 
matter in its three states—solid, liquid and
