The point? I haven’t the slightest idea. I don’t know why you posted the things you did. I only know that you did. Out of deference to your general retraction I shall not scrounge through the record to re-evaluate your intent in light of this parapgraph.
re: cogito
First an easy one. “Seeming” would seem to be a nounification of seems, thus it would be a perception.
Now for something meaty.
Let us begin with the definition you have offered for nothing, particularly the notion that any variation implies an existent thing. I have no problems accepting this definition and the implication it forces upon us (implication only, not causal relationship.)
For clarity, let’s establish a notation: Perception(“A”) means a perception with characteristic “A”. Characteristic, here, is kept purposely vague. We shall allow it to stand for the content of a perception, a property of the content, a property of the perception, etc. I do not think this amiguity will cause problems, but if it does we can go back and pin things down. Now let us look at what can be concluded given diffeent levels of confidence in our perceptions.
I) Let us assume that perceptions do indeed vary.
In other words, our perception of memory is if not accurate at least a reliable indicator that different perceptions occur at different times.
[ol]
[li]Perception(“change”) -> “something(s)” exists. [/li]This is the implication from definition. We cannot, at this time, know anything about the something(s) other than that it/they exist. “Something(s)” might be distinct from the perception(s), or “something(s)” might be only the perceptions it/themselves varying without external influence.
[li]Perception(“label”) -> “label” exists. We may follow this form for any perception we choose, but the symbols are empty of any additional meaning. Whatever “label” we substitute is indistinguishable from the unound “something(s)”. Placing any label with restrictive connotations into this conclusion serves only to promote confusions of meaning, since no restrictive connotations can be supported by this argument.[/ol][/li]At times, Begbert2, it seems that this is the argument you are trying to make. But then you try to use “I” as if the symbol carried additional meanings and restrictions, such as when you draw upon the Stanford site’s argument of subjectivity.
II) Let us assume (I) and presume that perceptions of variance within perception(s) are valid indicators of variance.
In other words, if presented with perceptions of “hunger” and “tree” we can presume that a variance does indeed exist either within a songle perception (encompassing both “tree” and “hunger” ) or between multiple perceptions that exhibit real difference. For simplicity’s sake, let us allow this presumption across all characeristics that we allow for perception.
[ol][li]Perception(“change”) -> “something(s)” exists. As above.[/li][li]Perception(“label”) -> “label” exists. At this point, we can make substitutions for “label” which are meaningful on one side of the implication. For instance:[/li][li]Perception(“tree”) -> “tree” exists.[/li][li]Perception(“thought”) -> “thought” exists.[/li][li]Perception(“I”) -> “I” exists.[/li]In all such cases, the “label” on the left side of teh implication is actually restrictive. It indicates a specific characteristic of perception which we have presumed represents a real distinction among the full set of our perception(s). However, the label on the right remains unbounded, for we have no mechanism with which to restrict the possibilities for “label’s” existence. As in (I), this “label” is a generic “something(s)” which might be external to the full set of our perception(s) or simply the perception(s) themselves.
We can, however, take things a step further with (II) by noting that the recognition of a "label"ed characteristic is itself a variance in perception. Thus
[li]Perception(“label(label)”) -> the label “label” exists.[/li][li]Perception(“label(thought)”) -> the label “thought” exists. In this case, both sides of the implication have a restricted meaning, though perhaps not the intuitive one. The left side, as above, indicates a real distinctin in a characteristic of perception. The right side indicates that the “something(s)” which exists can now be bound within the full set of perception(s). In other words, no matter whether the existence implied in (I) is extenal to perception(s), internal to perception(s), or a combination of both, we know that the ‘label “thought”’ can be completely internal. It’s a slight distinction, but it’s the first time we have been able to place even the slightest bound on “something(s)”.[/ol][/li]
III) Let us assume (I) and (II) and presume that perceptions of variance within perception accurately reflect real distinctions in the characteristics of existing perceptions.
This stronger for of (II) allows us, for instance, to conclude that perceptions with the characteristic “hunger” are different from perceptions with the characteristc “thought”. Thus.
[ol][li]Perception(“change”) -> “something(s)” exists. As above.[/li][li]Perception(“label”) -> “label” exists. Now, “label” has a meaning on both sides of the implication. The left side, as before, indicates a specific characteristic of perception. The right side indicates a set of perceptions to which that characteristic maps. However, that mapping is associative only. We still have established no causal connection. Thus, the set of perceptions that map to Perception(“anger”) exist, but this does not imply that any existing thing is angry nor does it imply that an existing thing that was angry would imply that set (or any subset) of perceptions exist. So, we have:[/li][li]Perception(“tree”) -> “tree” exists.[/li][li]Perception(“thought”) -> “thought” exists.[/li][li]Perception(“I”) -> “I” exists.[/li]But in each case, it is a set of perceptions being implied, not any external existent object. In the case of “thought”, this pretty much takes us to where Russell went. In the case of “I”, it takes us to a set of perceptions characterized by subjectivity, which is where the Stanford site takes off. Without that takeoff, “I” exist in this case does establish an identity relationship to a set of perceptions, but that relationship is descriptive only, it carries no implication beyond the associative mapping.[/ol]
IV) Let us assume (I) and (II) and (III) and presume that the real distinctions in the characteristics of existing perceptions indicate real distinction in existing objects external to the full set of perception(s).
In other words, if we see a tree, then something is “out there” (though it doesn’t need to be anything like what we perceive.) This is the “escape from solipsism” card. Thus:
[ol][li]Perception(“change”) -> “something(s)” exists. As above.[/li][li]Perception(“label”) -> “label” exists. restrictive on both sides of the implication. In this case, the right side carries the additional restriction that the perceptions mapping to “label” have an existing referent external to the full set of perception(s). For instance:[/li][li]Perception(“tree”) -> “tree” exists.[/li][li]Perception(“thought”) -> “thought” exists.[/li][li]Perception(“I”) -> “I” exists.[/li]A real thing exists which is perceived as “tree” (thoguh it need not be a tree).
Thought exists in a sense external to the perception of a thought. This would seem to be the minimum sense required to accept teh implication “thought -> thinker”.
I exist. My subjective identity has an existence external to my perception of subjective identity. Again, this does not require that the “I” of perception is similar to I. This, of course, is where the Stanford lead lands. It is also where Begbert2 seems to land most of the time.[/ol]
I very much doubt that anyone in this thread has issues with (I) or (II). We might even all agree to accept (III).
(IV), however, strikes me as very much unjustified if we pretend to be approaching ontology with penultimate skepticism. And, of course, if we do accept (IV) explicitely (rather than implicitly) it makes an available a more straightforward logical structure:
Perception of self; therefore I am.
ps
Still waiting for that proof of existence for nonobservational properties.
