Berkeley: The Objects of Human Knowlege


“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

Hume: Perceptions of the Senses


“Every one will readily allow, that there is a considerable difference between the perceptions of the mind, when a man feels the pain of excessive heat, or the pleasure of moderate warmth, and when he afterwards recalls to his memory this sensation, or anticipates it by his imagination. These faculties may mimic or copy the perceptions of the senses; but they never can entirely reach the force and vivacity of the original sentiment. The utmost we say of them, even when they operate with greatest vigour, is, that they represent their object in so lively a manner, that we could almost say we feel or see it”.
