…The question of perception;
Seeing That, Seeing As and Simple Seeing
Perception is the process by which we acquire information about the world around us using our five senses. Consider the nature of this information. Looking out of your window, you see that it is raining. Your perception represents the world as being like that. To perceive the world in this way, therefore, it is required that you possess concepts, that is, ways of representing and thinking about the world. In this case, you require the concept RAIN. Thus, seeing that your coffee cup is yellow and that the pencil is green involves the possession of the concepts COFFEE CUP, YELLOW, PENCIL and GREEN. Such perception is termed “perceiving that,” and is factive; that is, it is presupposed that you perceive the world correctly. To perceive that it is raining, it must be true that it is raining. You can also, though, perceive the world to be a certain way and yet be mistaken. This we can call, “perceiving as,” or in the usual case, “seeing as”. A stick partly submerged in water may not be bent but, nevertheless, you see it as bent. Your perception represents the stick as being a certain way, although it turns out that you are wrong. Much of your perception, then, is representational: you take the world to be a certain way, sometimes correctly, when you see that the world is thus and so, and sometimes incorrectly, when the world is not how you perceive it to be.
It also seems that there is a form of perception that does not require the possession of concepts (although this claim has been questioned). It is plausible to claim that cognitively unsophisticated creatures, those that are not seen as engaging in conceptually structured thought, can perceive the world, and that at times we can perceptually engage with the world in a non-conceptual way. You can tell that the wasp senses or perceives your presence because of its irascible behavior. When you are walking along the High Street daydreaming, you see bus stops, waste bins, and your fellow pedestrians. You must see them because you do not bump into them, but you do not see that the bus stop is blue or that a certain pedestrian is wearing Wrangler jeans. You can, of course, come to see the street in this way if you focus on the scene in front of you, but the claim here is that there is a coherent form of perception that does not involve such conceptual structuring. Let us call such baseline perceptual engagement with the world, “simple seeing”. This perception involves the acquisition of perceptual information about the world, information that enables us to visually discriminate objects and to successfully engage with them, but also information that does not amount to one having a conceptually structured representation of the world. (Dretske, 1969, refers to simple seeing as “non-epistemic” seeing, and refers to 'seeing that' as “epistemic” seeing).
You can, then, simply see the bus stop, or you can see that the bus stop is blue, or you can, mistakenly, see the bus stop as made of sapphire. These are all forms of perceptual experience, ways you have of causally engaging with the world using your sensory apparatus and ways that have a distinctive conscious or “phenomenological” dimension. Seeing in its various forms strikes your consciousness in a certain way, a way that you are now experiencing as you look at your computer screen. This article investigates the causal and epistemic roles of this perceptual experience.
A little more terminology: the term “sensation” can be used to refer to the conscious aspect of perception, but note that one can have such sensations even when one would not be said to be perceiving the world. When hallucinating, for example, one is having the sensations usually characteristic of perceptual experience, even though in such cases one's experience would not be described as perceptual.
