ON THE WONDERS OF THE WORLD,

is cut off through the year, pain is not felt. A proper disposition of the organ is also required; thus, if you touch a bean with crossed fingers, two are perceived, because by reason of the position, two organs appear to be involved, and the judging faculty the internal power that discerns sensory input is deceived. Man also suffers nausea and abomination from imagination, and sometimes he desires to eat and grows hungry from the memory of foods. But according to the good disposition of the organ, and according to how the species the sensory form or image of a thing is impressed upon it, the judgment varies: so that one judges wine to be of excellent flavor, another bitter; a man judges something hot, and after a short time, with the disposition changed, he will judge it cold, as is apparent in one bathing or suffering from a fever in a paroxysm. Note that just as in the other senses, so in these, for a sensation to occur, there is required an internal power, a received species, an organ, a medium (both internal and external, which is the sensible object), distance, and time, with those things added which were assigned above. Nevertheless, it is special in these two referring to taste and touch that the object of taste and touch acts upon the sense not only spiritually as in the remaining senses, but also really, because they are coarser and more material than the rest.

As often, therefore, as these things required for taste and touch are ordered, a proper sensation occurs. But if all, or many, are disordered, then according to the mode of disorder, wonderful errors occur in them beyond others.
