All the time that we are awake we are learning by means of our =senses=
something about the world in which we live and of which we form a part;
we are constantly aware of feeling, or hearing, or smelling, and, unless
we happen to be in the dark, of seeing; at intervals we taste. We call
the information thus obtained =sensation=.
When we have any of these sensations we commonly say that we feel, or
hear, or smell, or see, or taste, something. A certain scent makes us
say we smell onions; a certain flavour, that we taste apples; a certain
sound, that we hear a carriage; a certain appearance before our eyes,
that we see a tree; and we call that which we thus perceive by the aid
of our senses a =thing= or an =object=.
