Página 104 - The uniformity in the succession of events, otherwise called the law of causation, must be received, not as a law of the universe, but of that portion of 1 Logic, III.
Página 103 - I am convinced that any one accustomed to abstraction and analysis, who will fairly exert his faculties for the purpose, will, when his imagination has once learnt to entertain the notion, find no difficulty in conceiving that in some one for instance of the many firmaments into which sidereal astronomy now divides the universe, events may succeed one another at random, without any fixed law ; nor can anything in our experience, or in our mental nature, constitute a sufficient, or indeed any, reason...
