Seite 55 - ... pretend to explain the perception of distance, are themselves not at all perceived; nor are they in truth ever thought of by those unskilful in optics.
Seite 4 - ... existence, natural or real, distinct from their being perceived by the understanding. But with how great an assurance and acquiescence soever this principle may be entertained in the world, yet whoever shall find in his heart to call it in question may, if I mistake not, perceive it to involve a manifest contradiction. For what are the forementioned objects but the things we perceive by sense? and what do we perceive besides our own ideas or sensations? and is it not plainly repugnant that any...
Seite 118 - Nothing but my will, a thought of my mind; my thought only changing, the right hand rests, and the left hand moves. This is matter of fact, which cannot be denied: explain this, and make it intelligible, and then the next step will be to understand creation.
Seite 30 - If at any time I fpeak of light and rays as * coloured or endowed with colours, I would be " underftood not to fpeak philofophically and pro " perly, but grofsly, and according to fuch concep...
Seite 118 - If you do not understand the operations of your own finite mind, that thinking thing within you, do not deem it strange that you cannot comprehend the operations of that eternal, infinite Mind who made and governs all things, and whom the heaven of heavens cannot contain.
Seite 85 - Water occupies a lefs fpace in the fluid than in the folid ftate, and the contraction takes place juft before it reaches the point of congelation. Its •capacity or bulk has therefore been diminifhed, rather than enlarged, as this theory neceflarily fuppofes. It is argued, that we know no chemical combination in which the properties of one of the bodies combining are entirely loft, while thofe of the other are unaltered.
Seite 103 - We have only to fuppofe the quantity of caloric to be proportioned to the diftance ; and if a fmall quantity exifts in Mercury, no more heat may be excited than is done by a large quantity in Saturn. There ftill remain fome other points of inquiry concerning heat. It will be afked, how heat is produced, if it come not from the body of the fun ? I can only anfwer this queftion by referring it to the fource which is common to all material powers. The action of light upon body produces colours; that...
Seite 296 - Lastly, the idea of moral discipline proceeds entirely upon this principle. If I carefully persuade, exhort, and exhibit motives to another, it is because I believe that motives have a tendency to influence his conduct. If I reward or punish him, either with a view to his own improvement, or as an example to others, it is because I have been led to believe that rewards and punishments...
Seite 130 - The connexion between these propositions is not intuitive. There is required a medium, which may enable the mind to draw such an inference, if indeed it be drawn by reasoning and argument.
Seite 102 - It fhews that light produces heat merely by exciting, an infenfible action betwixt caloric and the particles of matter contained in bodies. It accounts for the want of heat in the upper regions of the atmofphere by the want of fufficient matter to produce the action of caloric ; and. for the cold of the night and the polar regions, by the want of that action which the fun produces.
