And first, we are to consider, that of Conceptions there are three Sorts, whereof one is of that which is present, which is Sense; another, of that which is past, which is Remembrance; and the third, of that which is future, which we call Expectation: all which have been manifestly declared in the second and third Chapters; and every of these Conceptions is Pleasure or Pain present. And first for the Pleasures of the Body which affect the Sense of Touch and Tast, as far forth as they be Organical, their Conceptions are Sense: so also is the Pleasure of all Exonerations of Nature: All which Passions I have before named, Sensual Pleasures; and their contrary, Sensual Pains: to which also may be added the Pleasures and Displeasures of Odours, if any of them shall be found Organical, which for the most Part they are not, as appeareth by this Experience which every Man hath, that the same Smells, when they seem to proceed from others, displease, though they proceed from our selves; but when we think they proceed from our selves, they displease not, though they come from others: the Displeasure of this is a Conception of Hurt thereby from those Odours, as being unwholesom, and is therefore a Conception of Evil to come, and not present. Concerning the Delight of Hearing, it is diverse, and the Organ it self not affected thereby: Simple Sounds please by Æquality, as the Sound of a Bell or Lute: insomuch as it seems, an Equality continued by the Percussion of the Object upon the Ear, is Pleasure; the Contrary is called Harshness, such as is Grating, and some other Sounds, which do not always affect the Body, but only sometime, and that with a Kind of Horrour beginning at the Teeth. Harmony, or many Sounds together agreeing, please by the same Reason as the Vnison, which is the Sound of equal Strings equally stretched. Sounds that differ in any Height, please by Inequality and Æquality alternate, that is to say, the higher Note striketh twice, for one Stroke of the other, whereby they strike together every second Time; as is well proved by Galileo, in the first Dialogue concerning local Motion: where he also sheweth, that two Sounds differing a fifth, delight the Ear by an Æquality of striking after two Inequalities; for the higher Note striketh the Ear thrice, while the other strikes but twice. In like Manner he sheweth wherein consisteth the Pleasure of Concord, and the Displeasure of Discord, in other Difference of Notes. There is yet another Pleasure and Displeasure of Sounds, which consisteth in Consequence of one Note after another, diversified both by Accent and Measure; whereof that which pleaseth is called Air; but for what Reason Succession in Tone and Measure is more Air than another, I confess I know not; but I conjecture the Reason to be, for that some of them imitate and revive some Passion which otherwise we take no Notice of, and the other not; for no Air pleaseth but for a time, no more doth Imitation. Also the Pleasures of the Eye consist in a certain Æquality of Colour: for Light, the most glorious of all Colours, is made by equal Operation of the Object; whereas Colour is perturbed, that is to say, unequal Light, as hath been said, Chap. 2. Sect. 8. And therefore Colours, the more Equality is in them, the more resplendent they are: and as Harmony is pleasure to the Ear, which consisteth of divers Sounds; so perhaps may some Mixture of divers Colours be Harmony to the Eye, more than another Mixture. There is yet another Delight by the Ear, which happeneth onely to Men of skill in Musick, which is of another Nature, (and not as these) Conception of the present, but rejoycing of their own Skill; of which nature are the Passions of which I am to speak next.
