CHAPTER IX. WHETHER WHAT APPEARS TO OUR SENSES AND IMAGINATIONS BE TRUE OR NOT.
The Stoics say that what the senses represent is true; what the imagination, is partly false, partly true. Epicurus that every impression of the sense or imagination is true, but of those things that fall under the head of opinion, some are true, some false: sense gives us a false presentation of those things only which are the objects of our understanding; but the imagination gives us a double error, both of things sensible and things intellectual. Empedocles and Heraclides, that the senses act by a just accommodation of the pores in every case; everything that is perceived by the sense being congruously adapted to its proper organ.
CHAPTER X. HOW MANY SENSES ARE THERE?
The Stoics say that there are five senses properly so called, seeing, hearing, smelling, tasting, and touching. Aristotle indeed doth not add a sixth sense; but he assigns a common sense, which is the judge of all compounded species; into this each sense casts its proper representation, in which is discovered a transition of one thing into another, like as we see in figure and motion where there is a change of one into another. Democritus, that there are divers species of senses, which appertain to beings destitute of reason, to the gods, and to wise men.
CHAPTER XI. HOW THE ACTIONS OF THE SENSES, THE CONCEPTIONS OF OUR MINDS, AND THE HABIT OF OUR REASON ARE FORMED.
The Stoics affirm that every man, as soon as he is born, has a principal and commanding part of his soul, which is in him like a sheet of writing-paper, to which he commits all his notions. The first manner of his inscribing is by denoting those notions which flow from the senses. Suppose it be of a thing that is white; when the present sense of it is vanished, there is yet retained the remembrance; when many memorative notions of the same similitude do concur, then he is said to have an experience; for experience is nothing more than the abundance of notions that are of the same form met together. Some of these notions are naturally begotten according to the aforesaid manner, without the assistance of art; the others are produced by discipline, learning, and industry; these only are justly called notions, the others are prenotions. But reason, which gives us the denomination of rational, is completed by prenotions in the first seven years. The conception of the mind is the vision that the intelligence of a rational animal hath received; when that vision falls upon the rational soul, then it is called the conception of the mind, for it hath derived its name from the mind [Greek omitted] from [Greek omitted]. Therefore these visions are not to be found in any other animals; they only are appropriated to gods and to us men. If these we consider generally, they are phantasms; if specifically, they are notions. As pence or staters, if you consider them according to their own value, are simply pence and staters; but if you give them as a price for a naval voyage, they are called not merely pence, etc., but your freight.
