OF DIFFERENT CAUSES THAT PRODUCE SENSATION.
We ought carefully to observe, that one Sensation has commonly more than one cause in the mind. It is, if I dare venture to make use of the term, a certain dose produced by Force and Variety. Genius consists in knowing how to strike several organs at once; and if we examine different writers, we shall perhaps perceive, that the best of them, and those who have pleased most, are those who have excited in our Mind most Sensations at one time.
Pray observe the multiplicity of Causes. We like to view a garden finely laid out, better than a confusion of trees. 1. Because our prospect, which would be confined, is not so. 2. Every walk is one, and forms one grand object; whereas, amidst confusion, every tree is one object, and a little one. 3. We see an arrangement which we were not accustomed to see. 4. We are pleased with the pains which have been taken. 5. We admire the care they take perpetually to resist Nature, which by spontaneous productions would put every thing in confusion. This is so true, that a garden quite neglected is intolerable. Sometimes the difficulty of a work, sometimes the easiness of it, pleases us; and, as in a magnificent garden we admire the grandeur and expence of its owner, we observe sometimes with delight, that they have had the art to please us with small expence and labour.
Gaming pleases us, because it satisfies our avarice, that is, our hope of possessing more: it flatters our vanity by an idea of that preference which fortune gives us, and the notice which others take of our luck: it satisfies our curiosity by presenting a sort of show to us. In a word, it gives us all the different pleasures of surprize.
Dancing pleases us by its nimble activity; by a certain grace; by the beauty and variety of attitudes; by its harmony with the music; the person who dances being, as it were, an instrument which accompanies it: but, above all, it pleases us by a particular disposition of our brain, by which it is so constituted that it refers and associates the idea of all the motions to certain other motions, and the greatest part of the attitudes, to other attitudes.
