7. Men are differently furnished with these, according to the different objects they converse with.
Men then come
to be furnished with fewer or more simple ideas from without, according as the objects they converse with afford
greater or less variety; and from the operations of their minds within, according as they more or less reflect on
them. For, though he that contemplates the operations of his mind, cannot but have plain and clear ideas of them;
yet, unless he turn his thoughts that way, and considers them attentively, he will no more have clear and distinct
ideas of all the operations of his mind, and all that may be observed therein, than he will have all the particular
ideas of any landscape, or of the parts and motions of a clock, who will not turn his eyes to it, and with attention
heed all the parts of it. The picture, or clock may be so placed, that they may come in his way every day; but yet
he will have but a confused idea of all the parts they are made up of, till he applies himself with attention, to
consider them each in particular.
