Berkeley: Ideas, Sensations, Notions

Zitat

“All our Ideas, Sensations, Notions or the things which we perceive by whatsoever Names they may be distinguish’d, are visibly Inactive, there is nothing of Power or Agency included in them.” (Of the Principles of Human Knowledge, §25) #Berkeley #Ideas #Sensations #Notions

Berkeley: Abstract General Ideas

Zitat

“By observing how ideas become general we may the better judge how words are made so. And here it is to be noted that I do not deny absolutely there are general ideas, but only that there are any ABSTRACT GENERAL IDEAS”. (Intro., §12) #Berkeley #AbstractGeneralIdeas

Russell: Certain Knowledge

Zitat

“Is there any knowledge in the world which is so certain that no reasonable man could doubt it? This question, which at first sight might not seem difficult, is really one of the most difficult that can be asked. When we have realized the obstacles in the way of a straightforward and confident answer, we shall be well launched on the study of philosophy–for philosophy is merely the attempt to answer such ultimate questions, not carelessly and dogmatically, as we do in ordinary life and even in the sciences, but critically, after exploring all that makes such questions puzzling, and after realizing all the vagueness and confusion that underlie our ordinary ideas.” (Chap. I) #Russell #knowledge #ideas

Berkeley: The Objects of Human Knowlege

Zitat

“IT is evident to any one who takes a Survey of the Objects of Human Knowlege, that they are either Ideas actually imprinted on the Senses, or else such as are perceiv’d by attending to the Passions and Operations of the Mind, or lastly Ideas formed by help of Memory and Imagination; either compounding, dividing, or barely representing those originally perceiv’d in the aforesaid ways.” (§1) #Berkeley #ObjectsOfHumanKnowledge

Berkeley: My Self

Zitat

“But besides all that endless variety of Ideas or Objects of Knowlege, there is likewise something which knows or perceives them, and exercises divers Operations, as Willing, Imagining, Remembering, &c. about them. This perceiving, active Being is what I call Mind, Spirit, Soul or my Self.” (§2) #Berkeley #ideas #ObjectsOfKnowledge #mind #mySelf
