can affect; and (2) since it will prove that every proposition of practical Ethics is false, if it can shew that an eternal reality is either the only real thing or the only good thing. Most metaphysical writers, believing in a reality of the latter kind, do thus imply the complete falsehood of every practical proposition, although they fail to see that their Metaphysics thus contradicts their Ethics. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . |

| 69. | But the theory, by which I have defined Metaphysical Ethics, is not that Metaphysics has a logical bearing upon the question involved in practical Ethics 'What effects will my action produce?,' but that it has such a bearing upon the fundamental ethical question, 'What is good in itself?.' This theory has been refuted by the proof, in Chap. I, that the naturalistic fallacy is a fallacy; it only remains to discuss certain confusions which seem to have lent it plausibility. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . |

| 70. | One such source of confusion seems to lie in the failure to distinguish between the proposition 'This is good,' when it means 'This existing thing is good,' and the same proposition, when it means 'The existence of this kind of thing would be good'; . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . |

| 71. | and another seems to lie in the failure to distinguish between that which suggests a truth, or is a cause of our knowing it, and that upon which it logically depends, or which is a reason for believing it: in the former sense fiction has a more important bearing on Ethics than Metaphysics can have. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . |

| 72. | But a more important source of confusion seems to lie in the supposition that 'to be good' is identical with the possession of some supersensible property, which is also involved in the definition of 'reality.' . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . |

| 73. | One cause of this supposition seems to be the logical prejudice that all propositions are of the most familiar type—that in which subject and predicate are both existents. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . |
