the design argument is a type of a priori argument

The argument from biological information, like the argument from biochemical complexity, seems incapable of standing alone as an argument for God’s existence. Similarly, if we already have adequate reason to believe that God exists, then design inferences can enable us to distinguish features of the world that merely happen from features of the world that are deliberately brought about by the agency of God. Weaknesses of the design argument (You should learn David Hume’s criticisms – ‘Dialogues concerning Natural Religion’ 1779). This is an argument in which the premises are supposed to support the conclusion in such a way that if the premises are true, it is improbable that the conclusion would be false. Pursuing a strategy that has been adopted by the contemporary intelligent design movement, John Ray, Richard Bentley, and William Derham drew on scientific discoveries of the 16th and 17th Century to argue for the existence of an intelligent Deity. When joined with other proofs for God’s existence (cosmological, ontological, moral etc) the design argument strengthens the probability of the existence of God. Among the classical versions are: (1) the “Fifth Way” of St. Thomas Aquinas; (2) the argument from simple analogy; (3) Paley’s watchmaker argument; and (4) the argument from guided evolution. By showing that the argument from design fails, Hume hopes to prove that religious belief cannot possibly be based on reason. Analysis Of William Paley's The Argument From Design At the end of this period, it compares all of the sequences with the target sequence METHINKS IT IS LIKE A WEASEL and keeps the sequence that most closely resembles it. Type: Knowledge: A Priori Definition: Knowledge or arguments based deductions from first principles. Organisms that have, say, a precursor to a fully functional cilium are no fitter than they would have been without it, but there is nothing in Darwinian theory that implies they are necessarily any less fit. Therefore some intelligent being exists by whom all natural things are directed to their end; and this being we call God (Aquinas, Summa Theologica, Article 3, Question 2). The Cosmological and Teleological Arguments are a posteriori, since at least one of their premises is a posteriori. First, Hume rejects the analogy between the material universe and any particular human artifact. Just as the purposive quality of the cumulative-step computer program above is best explained by intelligent design, so too the purposive quality of natural selection is best explained by intelligent design. Robin Collins defends a more modest version of the fine-tuning argument that relies on a general principle of confirmation theory, rather than a principle that is contrived to distinguish events or entities that are explained by intelligent design from events or entities explained by other factors. (True premise/All A are B) * 30 is a multiple of ten. While Schlesinger is undoubtedly correct in thinking that we are justified in suspecting design in the case where John wins three consecutive lotteries, it is because—and only because—we know two related empirical facts about such events. In response, one might be tempted to argue that there is one context in which scientists employ the design inference without already having sufficient reason to think the right sort of intelligent agency exists.

The Classical Versions of the Design Argument, Contemporary Versions of the Design Argument, The Argument from Irreducible Biochemical Complexity, The Argument from Suspicious Improbability, The Scientifically Legitimate Uses of Design Inferences. Next, Meyer argues that the probability of the design explanation for the origin of biological information is considerably higher: [O]ne can detect the past action of an intelligent cause from the presence of an information-rich effect, even if the cause itself cannot be directly observed. According to the Chance Lottery Hypothesis, John Doe’s numbers were drawn by chance. Second, and more obviously, we do not have any past experience with the genesis of worlds and are hence not in a position to know whether the existence of fine-tuned universes are usually explained by the deliberate agency of some intelligent agency. Theories of chemical necessity are problematic because chemical necessity can explain, at most, the development of highly repetitive ordered sequences incapable of representing information. This design argument, or, as its sometimes called, the teleological argument, has probably been the most influential argument for the existence of God throughout most of history. It then begins breeding from this new sequence in exactly the same way. Argumentum a fortiori (literally "argument from the stronger") (UK: / ˈ ɑː f ɔːr t i ˈ oʊ r i /, US: / ˈ eɪ f ɔːr ʃ i ˈ ɔːr aɪ /) is a form of argumentation that draws upon existing confidence in a proposition to argue in favor of a second proposition that is held to be implicit in, and even more certain than, the first. The mere fact that certain sequences take a certain shape that we can see meaning or value in, by itself, tells us nothing obvious about the probability that it is the result of intelligent design. While each of the design inferences in these arguments has legitimate empirical uses, those uses occur only in contexts where we have strong antecedent reason for believing there exist intelligent agents with the ability to bring about the relevant event, entity, or property. A priori vs. a posteriori A deductive argument can be said to be ‘a priori’ as it does not depend upon external validation. According to Aquinas’s Fifth Way: We see that things which lack knowledge, such as natural bodies, act for an end, and this is evident from their acting always, or nearly always, in the same way, so as to obtain the best result. A Posteriori Definition: Knowledge or arguments based on experience or empirical evidence. The argument from biological information is concerned with an explanation of how it is that the world went from a state in which it contained no living organisms to a state in which it contained living organisms; that is to say, it is concerned with the explanation of the very first forms of life. U. S. A. there exists so much intricate detail, design, and purpose in the world that we must suppose a creator. undertaking it is to deduce God's existence from the very definition of God. The Design Argument is a good example of an a posteriori argument. The argument concludes that intelligent design is the most probable explanation for the information present in large biomacromolecules like DNA, RNA, and proteins. Pre-biotic natural selection and chemical necessity cannot, as a logical matter, explain the origin of biological information. Further, Koran 31:20 asks “Do you not see that Allah has made what is in the heavens and what is in the earth subservient to you, and made complete to you His favors outwardly and inwardly?” While these verses do not specifically indicate which properties or features of the world are evidence of God’s intelligent nature, each presupposes that the world exhibits such features and that they are readily discernable to a reasonably conscientious agent. It is worth noting that Aquinas’s version of the argument relies on a very strong claim about the explanation for ends and processes: the existence of any end-directed system or process can be explained, as a logical matter, only by the existence of an intelligent being who directs that system or process towards its end. Yet why should not this answer serve for the watch as well as for [a] stone [that happened to be lying on the ground]?… For this reason, and for no other; namely, that, if the different parts had been differently shaped from what they are, if a different size from what they are, or placed after any other manner, or in any order than that in which they are placed, either no motion at all would have been carried on in the machine, or none which would have answered the use that is now served by it (Paley 1867, 1). Normally, existential claims don't follow from conceptual claims. An inductive argument, sometimes considered bottom-up logic, is one in which premises offer strong support for a conclusion, but one that is not a certainty. Stephen C. Meyer, “Evidence for Design in Physics and Biology: From the Origin of the Universe to the Origin of Life,” in Behe, Dembski, and Meyer (eds. While that experience will inductively justify inferring that some human agency is the cause of any information that could be explained by human beings, it will not inductively justify inferring the existence of an intelligent agency with causal powers that depart as radically from our experience as the powers that are traditionally attributed to God. Such an argument works like this: But, in doing so, they assume that nonliving chemicals instantiate precisely the kind of replication mechanism that biological information is needed to explain in the case of living organisms. It is noteworthy that each of these thinkers attempted to give scientifically-based arguments for the existence of God. Moral arguments say that moral values exist, and this is evidence for God. It is the very existence of the right kind of intelligent being that is at issue in the dispute over whether God exists. The design in any human artifact is the effect of having been made by an intelligent being. …the argument from design (or teleological argument) is that of the worth and purpose, or apparent design, to be found in the world. By the Prime Principle of Confirmation, then, John’s winning the lottery provides a reason to prefer the Theistic Lottery Hypothesis over the Chance Lottery Hypothesis. An a posteriori argument infers God’s existence from things that exist. Therefore, the design in the material universe is the effect of having been made by an intelligent creator. Suppose we flip a fair coin 1000 times and record the results in succession. Second, the claim that intelligent agents of a certain kind would (or should) see functional value in a complex system, by itself, says very little about the probability of any particular causal explanation. It is clear that John’s winning the lottery is vastly more probable under the Theistic Lottery Hypothesis than under the Chance Lottery Hypothesis. 1.relating to or denoting reasoning or knowledge that proceeds from theoretical deduction rather than from observation or experience. According to the Theistic Lottery Hypothesis, God wanted John Doe to win and deliberately brought it about that his numbers were drawn. This is Swinburne’s cumulative argument. A city is cumulatively complex since one can successively remove people, services, and buildings without rendering it unable to perform its function. https://quizlet.com/135323004/intro-to-philosophy-chapter-4-flash-cards • Cosmological: The existence of God is posited to explain the existence of (change in) the world. The Ontological Argument is a priori, since all of its premises are a priori. Without at least one of these two pieces of information, we are not obviously justified in seeing design in such cases. (Hume 1779 [1998], 35). As he puts the matter, in Volume 2 of Philosophical Theology, “the multitude of interwoven adaptations by which the world is constituted a theatre of life, intelligence, and morality, cannot reasonably be regarded as an outcome of mechanism, or of blind formative power, or aught but purposive intelligence” (Tennant 1928-30, 121). The teleological argument is a type of a priori argument. Dawkins considers two ways in which one might program a computer to generate the following sequence of characters: METHINKS IT IS LIKE A WEASEL. By this natural process, functionally complex organisms gradually evolve over millions of years from primordially simple organisms. While this claim surely implies that intelligent agents with the right causal abilities have a reason for bringing about such systems, it does not tell us anything determinate about whether it is likely that intelligent agents with the right causal powers did bring such systems about—because it does not tell us anything determinate about whether it is probable that such agents exist. For example, life would not be possible if the force of the big bang explosion had differed by one part in 1060; the universe would have either collapsed on itself or expanded too rapidly for stars to form. Unlike the proponent of the design argument, however, the court had an additional piece of information available to it: the court already knew that there existed an intelligent agent with the right causal abilities and motives to bring about the event; after all, there was no dispute whatsoever about the existence of Caputo. To understand Schlesinger’s argument, consider your reaction to two different events. Caputo, a member of the Democratic Party, was a public official responsible for conducting drawings to determine the relative ballot positions of Democrats and Republicans. These explanations proceed by asserting that the most complex nonliving molecules will reproduce more efficiently than less complex nonliving molecules. It is a type of argument based on experience of the world. The probability of getting the particular outcome is vanishingly small: 1 in 21000 to be precise. What matters for Paley’s argument is that works of nature and human artifacts have a particular property that reliably indicates design. Ontological argument, Argument that proceeds from the idea of God to the reality of God.It was first clearly formulated by St. Anselm in his Proslogion (1077–78); a later famous version is given by René Descartes.Anselm began with the concept of God as that than which nothing greater can be conceived. According to Behe, the probability of evolving irreducibly complex systems along Darwinian lines is sufficiently small that it can be ruled out as an explanation of irreducible biochemical complexity: An irreducibly complex system cannot be produced … by slight, successive modifications of a precursor system, because any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional…. Since the works of nature possess functional complexity, a reliable indicator of intelligent design, we can justifiably conclude that these works were created by an intelligent agent who designed them to instantiate this property. Given that we are justified in inferring intelligent design in the case of John’s winning three consecutive lotteries, we are even more justified in inferring intelligent design in the case of our winning two dozen much more improbable property lotteries. Now whatever lacks knowledge cannot move towards an end, unless it be directed by some being endowed with knowledge and intelligence; as the arrow is directed by the archer. The precise ordering of the four nucleotides, adenine, thymine, guanine, and cytosine (A, T, G, and C, for short), determine the specific operations that occur within a living cell and is hence fairly characterized as representing (or embodying) information. Robin Collins, “A Scientific Argument for the Existence of God,” in Michael J. Murray (ed. Design arguments say that certain things are so complex and functional they must have been designed by somebody like God. The mere fact that it is enormously improbable that an event occurred by chance, by itself, gives us no reason to think that it occurred by design. George N. Schlesinger, however, attempts to formalize the fine-tuning intuition in a way that avoids this objection. Design A Swap Module That Accepts Two Arguments Of The Real Data Type And Swaps Them. Over time, the replication of genetic material in an organism results in mutations that give rise to new traits in the organism’s offspring. I mean that the contrivances of nature surpass the contrivances of art, in the complexity, subtilty, and curiosity of the mechanism; and still more, if possible, do they go beyond them in number and variety; yet in a multitude of cases, are not less evidently mechanical, not less evidently contrivances, not less evidently accommodated to their end, or suited to their office, than are the most perfect productions of human ingenuity (Paley 1867, 13). A posteriori arguments. Assuming the Atheistic Single-Universe Hypothesis is true, the probability that the universe has the fine-tuned properties is very small—though it is not clear exactly how small. ... to the argument from design? For example, there is nothing in the argument that would warrant the inference that the creator of the universe is perfectly intelligent or perfectly good. If this highly speculative hypothesis is correct, then there is nothing particularly suspicious about the fact that there is a fine-tuned universe, since the existence of such a universe is inevitable (that is, has probability 1) if all every material universe is eventually realized in the multiverse. 2. Despite the fact that the probability of winning three consecutive 1-in-1,000 games is exactly the same as the probability of winning one 1-in-1,000,000,000 game, the former event is of a kind that is surprising in a way that warrants an inference of intelligent design. The first program randomly producing a new 28-character sequence each time it is run; since the program starts over each time, it incorporates a “single-step selection process.” The probability of randomly generating the target sequence on any given try is 2728 (that is, 27 characters selected for each of the 28 positions in the sequence), which amounts to about 1 in (10,000 x 1,000,0006). A. While the argument from irreducible biochemical complexity focuses on the probability of evolving irreducibly complex living systems or organisms from simpler living systems or organisms, the argument from biological information focuses on the problem of generating living organisms in the first place. It was that piece of information, together with (1), that enabled the court to justifiably conclude that the probability that an intelligent agent deliberately brought it about that the Democrats received the top ballot position 40 of 41 times was significantly higher than the probability that this happened by chance. A posteriori arguments B. Attitudes toward arguments for God’s existence 1. A priori arguments 2. This version of the fine-tuning argument proceeds by comparing the relative likelihood of a fine-tuned universe under two hypotheses: Assuming the Design Hypothesis is true, the probability that the universe has the fine-tuned properties approaches (if it does not equal) 1. Such thinkers, however, frequently maintain that the existence of God is needed to explain the purposive quality of the evolutionary process. Schlesinger’s fine-tuning argument also appears vulnerable to the same criticism as the other versions of the design argument (see Himma 2002). Accordingly, while the court was right to infer a design explanation in the Caputo case, this is, in part, because the judges already knew that the right kind of intelligent beings exist—and one of them happened to have occupied a position that afforded him with the opportunity to rig the drawings in favor of the Democrats. A posteriori is a term first used by Immanuel Kant and it means "from below" or "bottom-up". Thus, while chemical necessity can explain periodic order among nucleotide letters, it lacks the resources logically needed to explain the aperiodic, highly specified, complexity of a sequence capable of expressing information. Scientists have determined that life in the universe would not be possible if more than about two dozen properties of the universe were even slightly different from what they are; as the matter is commonly put, the universe appears “fine-tuned” for life. According to the argument, the appearance of design in nature is evidence for the existence of God. If all we know about the world is that John Doe won a lottery and the only possible explanations for this observation are the Theistic Lottery Hypothesis and the Chance Lottery Hypothesis, then this observation provides some reason to prefer the former. Contemporary biologist, Richard Dawkins (1986), uses a programming problem to show that the logic of the process renders the Darwinian explanation significantly more probable than the design explanation. Since natural selection can only choose systems that are already working, if a biological system cannot be produced gradually it would have to arise as an integrated unit, in one fell swoop, for natural selection to have anything to act on (Behe 1996, 39; emphasis added). Second, some physicists speculate that this physical universe is but one material universe in a “multiverse” in which all possible material universes are ultimately realized. Indeed, Hume argues that there is nothing there that would justify thinking even that there is just one deity: “what shadow of an argument… can you produce from your hypothesis to prove the unity of the Deity?
