likely to suggest experiments tending to throw light upon the 

 real properties of the phenomenon, than the following out such 

 an hypothesis. But to this end it is by no means necessary 

 that the hypothesis he mistaken for a scientific truth. On 

 the contrary, that illusion is in this respect, as in every 

 other, an impediment to the progress of real knowledge, hy 

 leading inquirers to restrict themselves arbitrarily to the 

 particular hypothesis which is most accredited at the time, 

 instead of looking out for every class of phenomena between 

 the laws of which and those of the given phenomenon any 

 analogy exists, and trying all such experiments as may tend 

 to the discovery of ulterior analogies pointing in the same 

 direction.
