Any incident which ferves as a caufe, either of pleafure or of pain, may be termed an exciting cauie if of pleafure, a pleafurable caufe c if of pain, a painful, afHi&ive~ or dolorific caufe a. V. d
Now the quantity of pleafure, or of pain, which a man is liable to C experience upon the application of an exciting caufe, fince they will fl not depend altogether upon that caufe, will depend in fome meafure 1i upon fome other circumftance or circumAances thefe circumftances, what&ever they be, may be termed circumftances influencing fenfibility VI.
Thefe circumftances will apply differently to different exciting C caufes; infomuch that to a certain exciting caufe, a certain circum- a itance ihall not apply at all, which iha!l apply with gréât force to Cc another exciting caufe. But without entering for the prefent into thefe e difUncUons, it may be of ufe to fum up all the circumftances which can be found to innuence the en~<3: of any exciting caufe. Thefe, as on a former occafion, it may be as well nrit to fum up together in the conclicA manner poffible, and afterwards to aUot a few words to thé feparate explanation of each article. They feem to be as follows i. Health. 2. Strength. 3. Hardinefs. Bodily Imperfection. Qyantity and quality of knowledge. 6. Strength of Intellectuat jpowers. 7. Firmnefs of mind. 8. Steadineis of mind. o. Bent of The exciting caufe, the pleafure or pain produced by tt, and the intention pro.duced by fuch pleafure or pain in the chara&er of à motive, are objets ~b intimately conne~ed, that, In what. follows, 1 fear 1 hâve not, on every occafion, been able to keep them fufficiently diftin~. 1 thought it neceffary to give the reader this warning; after which, lhould there be found any mch miftakes, it is to be hoped they will aot be produ6Uve of much confufion.
b Thus, in phyûcal bodies, the momentum of a ba!t put in modon by impulfe, will be influenced by the circumftance of gravity being in fome dlre&ions encreafed, in others diminifhed by it. So in a Mp, put in motion by the wind, the momentum and direalon will be influenced not only by the attra~ion of gravity, but by the mo. tion and refifiance of the water, and lèverai other circumftances.
