ble of those belonging to the touch, are heat and
cold, and solidity: all the rest, consisting almost wholly in the
sensible configuration, as smooth and rough; or else, more or less firm
adhesion of the parts, as hard and soft, tough and brittle, are obvious
enough.
2. Few simple Ideas have Names.
I think it will be needless to enumerate all the particular simple ideas
belonging to each sense. Nor indeed is it possible if we would; there
being a great many more of them belonging to most of the senses than we
have names for. The variety of smells, which are as many almost, if not
more, than species of bodies in the world, do most of them want names.
Sweet and stinking commonly serve our turn for these ideas, which in
effect is little more than to call them pleasing or displeasing; though
the smell of a rose and violet, both sweet, are certainly very distinct
ideas. Nor are the different tastes, that by our palates we receive
ideas of, much better provided with names. Sweet, bitter, sour, harsh,
and salt are almost all the epithets we have to denominate that
numberless variety of relishes, which are to be found distinct, not only
in almost every sort of creatures, but in the different parts of the
same plant, fruit, or animal. The same may be said of colours and
sounds. I shall, therefore, in the account of simple ideas I am here
giving, content myself to set down only such as are most material to our
present purpose, or are in themselves less apt to be taken notice of
though they are very frequently the ingredients of our complex ideas;
amongst which, I think, I may well account solidity, which therefore I
shall treat of in the next chapter.
CHAPTER IV.
IDEA OF SOLIDITY.
1. We receive this Idea from Touch.
The idea of SOLIDITY we receive by our touch: and it arises from the
resistance which we find in body to the entrance of any other body into
the place it possesses, till it has left it. There is no idea which we
receive more constantly from sensation than solidity. Whether we move or
rest, in what posture soever we are, we always feel something under us
that supports us, and hinders our further sinking downwards; and the
bodies which we daily handle make us perceive that, whilst they remain
between them, they do, by an insurmountable force, hinder the approach
of the parts of our hands that press them. THAT WHICH THUS HINDERS THE
APPROACH OF TWO BODIES, WHEN THEY ARE MOVED ONE TOWARDS ANOTHER, I
