  1. Since your post directly followed mine, I presumed you were referring to my post. I apologize if this was not the case. Just to clear the air, however, I do not think that first-level generalizations nor first level concepts are formed without conceptual processing. When a child first perceives a particular table, it can only identify it ostensively as an entity, as a particular thing, no more. Only after it has perceived at least two instances of tables, has noted their similarities and their differences from other non-table entities, does the child ostensively have the concept 'table.'
  2. I now have "The Logical Leap (TLL)" and have begun reading it, and so wanted to address this issue re: perception's role in induction. Plasmatic is creating a straw man argument here. I didn't say that there were any concepts that were perceptual "only." In fact, my post only addressed concept formation in the sense that a child directly perceives a *particular* table. What I implied was that the child first grasps first-level generalizations such as 'pushing this particular ball requires force to make it role' through direct perception. To quote directly from TLL, page 19 (asterix mi
  3. Hi Thomas, it has been a while indeed! I'll have to read the book before posting further on this subject. I know concept formation and induction are similar, but they are not the same thing, which was the general point of my post. After reading the book, I may start a seperate thread on this issue re: induction vs. concept formation and the role direct perception plays in each. Also, I know the importance of causation with respect to induction, but the key point is not just any causation, but formal (essential) causation.
  4. I haven't read Harriman's book yet, but are you suggesting that all concepts are formed by induction, or that causation is a special case of a concept that has to be formed by induction? I don't think concept formation and induction are the same thing. Causation is perceived directly, in the same manner as the child perceives a particular table. The child perceives the force required to push the ball directly. Causation, like all first level concepts, is directly available through perception. Saying all S is P (induction) is a different thing than first forming the concept S, and the conc
  5. This should be better clarified: Arbitrary--a claim for which there is *no* perceptual evidence. Possible--a claim for which there is at least *some* perceptual evidence. Probable--a claim which *most* of the perceptual evidence supports. Certain--a claim which *all* the contextually available perceptual evidence supports. Insofar as Pascal's wager is concerned, its major root fallacy is that it requires the equivocation between the arbitrary and possible. If its intended victim doesn't pretend that the *arbitrary* is the equivalent of the *possible*, then the entire argument
  6. While I think this is certainly true, it is far too kind--it doesn't take into account the harmful epistemological effects that are involved in believing in an omnipotent and omniscient being for which there is no perceptual evidence. It means sacrificing the one and only means you have of knowing reality (your perception and valid means of conceptualization) for the sake of an arbitrary claim. It means sacrificing your rationality and your means of validating existence for the sake of what? Social convention? Political gain? Acceptance by those who have chosen to sacrifice their rational
  7. The problem with this entire view is that it makes the explicit assumption that physics qua physics somehow contradicts the existence of a volitional consciousness. Physics per se is silent on the issue of consciousness. This, in fact, is a clear example of the fallacy of composition--the sum cannot be anything more than its constituent parts. By this line of reasoning, the perceived properties of water would have to be denied and abandoned since the individual gases hydrogen and oxygen (in isolation) clearly do not demonstrate any of the causal properties of liquid water. Even if, as yo
  8. The claim that what I perceive is not actually what I perceive is as old as Plato and reaches its pinnacle with Kant—it has no basis in reality and is simply arbitrary. If there is no free will then there is no such thing as science, logic or any other form of knowledge--the determinist was simply determined to think that his choice to believe determinism is true and I was simply determined to believe that what I perceive is actually what I perceive. Perception is not dubious, it is an irreducible primary. Indeed, it is the fact that I can perceive that I could have done otherwise that ma
  9. Thanks to KendallJ for the quotes from OPAR. The evidence for man's volitional consciousness is perceptual. To deny my volitional nature is to deny the *introspective* evidence available to me--I can perceive that I could have done otherwise. Whenever I chose A over B I know introspectively that I could have done otherwise and chosen B over A. As Dr. Peikoff points out in OPAR the type of causation that occurs when one billiard ball strikes another is one form of causation, but this does not exhaust the field. The law of causation stipulates that an entity will act according to its n
  10. I think this pretty much sums up my view as well. When one makes a claim to have discovered a significant flaw in a philosopher's ideas, it is inadequate to simply dismiss her formulations by implicitly re-stating the ideas of her philosophical predecessors (Plato and Kant) when her epistemology indeed corrects the errors of those predecessors. Furthermore, one has to demonstrate a more than superficial grasp of the ideas one claims to be refuting, and a more than superficial grasp of the errors of her philosophical predecessors. This is particularly true when one is grappling with a subjec
  11. This entire argument rests on the fallacy of distribution, an equivocation on the term ‘human life’, and on a completely fallacious definition of the concept ‘mind’. In 1) the term ‘human life’ is first used to mean all human beings, and its meaning is then switched to mean ‘separate cells of the body.’ An organism (in this case man) is not the same thing as the cells that compose it. This is the fallacy of distribution—equivocating between a thing and whatever composes a thing, distributively. In 2) the fallacy of distribution is also apparent, along with an erroneous implicit defin

  13. Yes. In order to reach the conceptual level at which you can *explicitly* grasp the axiomatic concept 'existence', and that existence refers to all things that exist, you have to have already grasped many, many lower level concepts. But the very process of conceptualization *implicitly* presupposes that something exists. The important thing to keep in mind is that there is a distinction between the *explicit* grasp of a concept and presupposing it *implicitly* during conceptualization. You were already abstracting, differentiating and integrating long before you could explicitly identify t
  14. How concepts are grasped and how they are defined are two very different things. Also, axiomatic concepts are unique in that they have certain characteristics that distinguish them from all other concepts. Existence is the broadest concept epistemologically because it subsumes all entities that exist. At the same time, however, existence is an axiomatic concept because of certain essential characteristics, one being that it can only be defined ostensively. Qua concept, existence is hierarchical, and, in fact it’s the highest (or broadest) concept on a very long conceptual chain. Conce
  15. You've hit the nail on the head. There is nothing immoral about emergency medical care per se (on the contrary, it is a bona fide medical speciality that meets a definite demand in medicine), but, as in so many other areas in our mixed economy, the immorality lies with government intrusion.
