ing of the kind, although so he
distinctly says. Rather, he appears to mean the direct converse, viz.,
that we cannot have the idea of gold or of weight present to the mind,
without having present also all the simple ideas of which those complex
ideas are compounded--in other words, not that the occurrence of any one
component necessarily calls up all the other components, and forms with
them the compound, but that the appearance of the compound brings with
it all its separate components.

But neither does this seem to be a strictly correct representation. I am
not sure that I can think of gold without thinking of yellowness, but I
am positive that I can without thinking of hardness. Nor is there any
doubt that the youngest child knows perfectly well what it means when,
trying to lift a stone, it calls the stone heavy, although it might not
be more difficult to make the stone itself than the child understand
what is meant by muscular contractility. I own that if it be here
demanded of me how a compound can be present unless every one of its
components be present also, I may under pressure be constrained to
suggest that possibly, after all, the very term _compound_ or _complex
idea_ may be somewhat of a misnomer, or at any rate that the
constituents of such an idea are much fewer than is commonly supposed.
Be it admitted that the idea, so styled, could not have been formed
without the instrumentality of other and previously-formed ideas, still
it does not follow that the instruments of production should for ever
after accompany the product. The rackful of dry toast which is brought
to you for breakfast could scarcely have been so neatly sliced without
the help of a knife, but the toast is not the less in bodily presence on
the breakfast-table because the knife that cut it has been left behind
in the kitchen. Neither, although you may probably be aware that salt,
suet, sugar, and spice enter into the composition of a Christmas
pudding, do you necessarily think of those separate ingredients when you
think of the pudding, any more than you would see them separately if you
saw the pudding. The only qualities which you apparently cannot help
thinking of when you think of the pudding are its size, shape, and
colour.

One word more about the assumed regularity in the succession of ideas.
That when you are repeating a familiar form of words or playing a
familiar piece of music, every word uttered or note struck, by reason of
