Our basic moral beliefs have two characteristics, Sidgwick found himself forced to conclude not entirely happily; they do not form any kind of unity, they are irreducibly heterogeneous; and their acceptance is and must be unargued. At the foundation of moral thinking lie beliefs in statements for the truth of which no further reason can be given. To such statements Sidgwick, borrowing the word from Whewell, gives the name intuitions. Sidgwick’s disappointment with the outcome of his own enquiry is evident in his announcement that where he had looked for Cosmos, he had in fact found only Chaos.
