CHAPTER XXI. Of the Evidence of the Law of Universal 

 Causation. 



PAGB 



1. The law of causality does not rest on an instinct . . 95 



2. But on an induction by simple enumeration . . 100 



3. In what cases such induction is allowable . . 102 



4. The universal prevalence of the law of causality, on what 



grounds admissible ..... 105 



CHAPTER XXII. Of Uniformities of Coexistence not dependent 

 on Causation. 



1. Uniformities of coexistence which result from laws of 



sequence ....... 110 



2. The properties of Kinds are uniformities of coexistence . Ill 



3. Some are derivative, others ultimate . . . 113 



4. "No universal axiom of coexistence . . . 114 



5. The evidence of uniformities of coexistence, how mea- 



sured 117 



6. When derivative, their evidence is that of empirical laws 117 



7. So also when ultimate ..... 119 



8. The evidence stronger in proportion as the law is more 



general ....... 120

CHAPTER XXIII. Of Approximate Generalizations, and Probable 

 Evidence. 



1. The inferences called probable, rest on approximate gene- 

 ralizations ...... 124 



2. Approximate generalizations less useful in science than 



in life . . . . . .124 



3. In what cases they may be resorted to . . 126 



4. In what manner proved . . . . .127 



5. With what precautions employed .... 130
