12. Knowledge Sources / A. A Priori Knowledge / 3. Innate Knowledge / c. Tabula rasa
The intellect has potential to think, like a tablet on which nothing has yet been written [Aristotle]
     Full Idea: The intellect is in a way potentially the object of thought, but nothing in actuality before it thinks, and the potentiality is like that of the tablet on which there is nothing actually written.
     From: Aristotle (De Anima [c.329 BCE], 429b31)
     A reaction: This passage is referred to by Leibniz, and is the origin of the concept of the 'tabula rasa'. Aristotle need not be denying innate ideas, but merely describing the phenomenology of the moment before a train of thought begins.
12. Knowledge Sources / B. Perception / 1. Perception
Perception of sensible objects is virtually never wrong [Aristotle]
     Full Idea: Perception of the special objects of sense is never in error or admits the least possible amount of falsehood.
     From: Aristotle (De Anima [c.329 BCE], 428b19)
     A reaction: This is, surprisingly, the view which was raised and largely rejected in 'Theaetetus'. It became a doctrine of Epicureanism, and seems to make Aristotle a thoroughgoing empiricist, though that is not so clear elsewhere. I think Aristotle is right.
Perception necessitates pleasure and pain, which necessitates appetite [Aristotle]
     Full Idea: Where there is perception there is also pleasure and pain, and where there are these, of necessity also appetite.
     From: Aristotle (De Anima [c.329 BCE], 413b23)
Why do we have many senses, and not just one? [Aristotle]
     Full Idea: A possible line of inquiry would be into the question for what purpose we have many senses and not just one.
     From: Aristotle (De Anima [c.329 BCE], 425b04)
Our minds take on the form of what is being perceived [Aristotle, by Mares]
     Full Idea: Aristotle famously holds that in perception our minds take on the form of what is being perceived.
     From: report of Aristotle (De Anima [c.329 BCE]) by Edwin D. Mares - A Priori 08.2
     A reaction: [References in Aristotle needed here...]
Why can't we sense the senses? And why do senses need stimuli? [Aristotle]
     Full Idea: Why is there not also a sense of the senses themselves? And why don't the senses produce sensation without external bodies, since they contain elements?
     From: Aristotle (De Anima [c.329 BCE], 417a03)
Sense organs aren't the end of sensation, or they would know what does the sensing [Aristotle]
     Full Idea: Flesh is not the ultimate sense-organ. To suppose that it is requires the supposition that on contact with the object the sense-organ itself discerns what is doing the discerning.
     From: Aristotle (De Anima [c.329 BCE], 426b16)
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / c. Primary qualities
Many objects of sensation are common to all the senses [Aristotle]
     Full Idea: Common sense-objects are movement, rest, number, shape and size, which are not special to any one sense, but common to all.
     From: Aristotle (De Anima [c.329 BCE], 418a18)
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities
Some objects of sensation are unique to one sense, where deception is impossible [Aristotle]
     Full Idea: Now I call that sense-object 'special' that does not admit of being perceived by another sense and about which it is impossible to be deceived.
     From: Aristotle (De Anima [c.329 BCE], 418a15)
12. Knowledge Sources / B. Perception / 3. Representation
In moral thought images are essential, to be pursued or avoided [Aristotle]
     Full Idea: In the thinking soul, images play the part of percepts, and the assertion or negation of good or bad is invariably accompanied by avoidance or pursuit, which is the reason for the soul's never thinking without an image.
     From: Aristotle (De Anima [c.329 BCE], 431a15)
12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
We experience qualities as of objects, not on their own [Harré/Madden]
     Full Idea: It seems clear that we are never presented with a quality except of some object.
     From: Harré,R./Madden,E.H. (Causal Powers [1975], 3.II)
     A reaction: I'm not convinced that that 'seems clear'. The idea of sense-data is that while it seems to be of an object, reason suggests that the experience of the quality must precede the object assembled thereby. How do you arbitrate?
12. Knowledge Sources / B. Perception / 6. Inference in Perception
Inference in perception is unconvincingly defended as non-conscious and almost instantaneous [Harré/Madden]
     Full Idea: To the objection that one is never aware of inferences in sensation, the unconvincing reply comes that such inferences are automatic, telescoped, non-discursive and unconscious.
     From: Harré,R./Madden,E.H. (Causal Powers [1975], 3.II)
     A reaction: I think the 'unconvincing' reply is a bit more convincing in the light of modern research on the brain, which presents everything it does in a far less conscious light than the traditional view. Even reason seems barely conscious.
12. Knowledge Sources / C. Rationalism / 1. Rationalism
We may think when we wish, but not perceive, because universals are within the mind [Aristotle]
     Full Idea: Perception is of particular things, but knowledge is of universals, which are in a way in the soul itself. Thus a man may think whenever he wishes, but not perceive.
     From: Aristotle (De Anima [c.329 BCE], 417b22)
12. Knowledge Sources / D. Empiricism / 2. Associationism
Humean impressions are too instantaneous and simple to have structure or relations [Harré/Madden]
     Full Idea: The Humean event, the impression, basic to his epistemology, is, as we have seen, instantaneous in nature, punctiform and elemenentary, and from this characterisation follows its atomicity, its lack of internal connections with anything else.
     From: Harré,R./Madden,E.H. (Causal Powers [1975], 6.IV)
     A reaction: This simple point about Humean associationism is the key to grasping the whole hideous worldview that has gripped twentieth century philosophy. How many impressions make up an apple? And why do they sum to make something?
