Astrology and Pseudoscience

When people started to classify things in the world, different types of divisions also started being etched on history. Why do men classify? What are these divisions for? Perhaps, many would say that classification is motivated by convenience. In a grocery store, the goods are arranged according to certain factors. One of those is according to purpose—hygienic needs are situated all together in a rack while food, with its further subdivisions, are on others. Through this classification, people are able to easily look for what they need by simply looking at the signage. However, there are also classifications that are motivated by the desire to degrade. An instance of this is the chronic skin color disparity between the 'blacks and whites.' The whites are more privileged in the society while the blacks are seen as criminals and slaves. In the Philosophy of Science, there is also what I call the " The Great Divide " which separates what is science from what is pseudo-science. Just like in the previous examples of classification, it is important to inquire as well regarding the purpose of this demarcation. What are the criteria for saying that a theory is scientific or not? In the discussion of the demarcation, astrology would be a good reference point. Astrology used to be very popular in the ancient times. Through the movements of the sun, moon, and planets as well as its manifestations in nature, astrology was able to predict fate expressed through the Zodiac signs. Contrary to popular belief, Tetrabiblos by Ptolemy has proven its complex methodology (Thagard 224). However, for Karl Popper, a theory is scientific if it is falsifiable or open to refutations. Running against dogmatism, Popper criticized three theories namely the Marxist theory of history, psychoanalysis, and individual psychology which seemed to have attained the scientific status. He felt that these theories " though posing as sciences, had in fact more in common with primitive myths than with science; that they resembled astrology rather than astronomy (Popper 2). " Like astrology, the three enjoy immense explanatory power because the world teems with confirmations of the theory. Their explanatory power comes from the vagueness of its statements which allows them to veer away from falsification or the test of the legitimacy of their theory. For example, your horoscope would tell you that you will be meeting an important person in your life within the week. The vagueness of the statement would definitely allow the theory to hold true since the person would consciously search for a confirming evidence. For Popper, there is danger in looking at confirming evidences only for a theory which proves to be an explanation of all possible phenomena closes its doors to progress. Falsifying a theory is finding an instance wherein its prediction does not hold true and those falsifying instances make the theory narrower. Hence, the applicability of the theory is strengthened as it is limited to specific cases which makes astrology, with its vague predictions, a pseudo-science.

Why do men classify? What are these divisions for? Perhaps, many would say that classification is motivated by convenience. In a grocery store, the goods are arranged according to certain factors.

In the Philosophy of Science, there is also what I call the “The Great Divide” which separates what is science from what is pseudo-science. Just like in the previous examples of classification, it is important to inquire as well regarding the purpose of this demarcation. What are the criteria for saying that a theory is scientific or not? In the discussion of the demarcation, astrology would be a good reference point. Astrology used to be very popular in the ancient times. Through the movements of the sun, moon, and planets as well as its manifestations in nature, astrology was able to predict fate expressed through the Zodiac signs. Contrary to popular belief, Tetrabiblos by Ptolemy has proven its complex methodology (Thagard 224). However, for Karl Popper, a theory is scientific if it is falsifiable or open to refutations. Running against dogmatism, Popper criticized three theories namely the Marxist theory of history, psychoanalysis, and individual psychology which seemed to have attained the scientific status. He felt that these theories “though posing as sciences, had in fact more in common with primitive myths than with science; that they resembled astrology rather than astronomy (Popper 2).” Like astrology, the three enjoy immense explanatory power because the world teems with confirmations of the theory. Their explanatory power comes from the vagueness of its statements which allows them to veer away from falsification or the test of the legitimacy of their theory. For example, your horoscope would tell you that you will be meeting an important person in your life within the week. The vagueness of the statement would definitely allow the theory to hold true since the person would consciously search for a confirming evidence. For Popper, there is danger in looking at confirming evidences only for a theory which proves to be an explanation of all possible phenomena closes its doors to progress. Falsifying a theory is finding an instance wherein its prediction does not hold true and those falsifying instances make the theory narrower. Hence, the applicability of the theory is strengthened as it is limited to specific cases which makes astrology, with its vague predictions, a pseudo-science. On the other hand, for Paul Thagard, “falsifiability provides no criterion for rejecting astrology as pseudo-scientific (226).” Rather, three elements namely theory, community, and historical context are necessary in giving status to a theory and these can be summed up into two statements that make up Thagard’s principle of demarcation. “A theory or discipline which purports to be scientific is pseudoscientific if and only if: 1) it has been less progressive than alternative theories over a long period of time, and faces many unsolved problems; but 2) the community of practitioners makes little attempt to develop the theory towards solutions of the problems, shows no concern for attempts to evaluate the theory in relation to others, and is selective in considering confirmations and disconfirmations (Thagard 228).” Astrology, since Ptolemy, remained stagnant due to the lack of interest of the community of practitioners to solve surfacing issues and develop the study further. The stagnation allowed alternative theories such as psychology to be on the rise therefore replacing astrology. Both Popper and Thagard assert that astrology is pseudo-scientific but differ in their reasons for saying so. Popper locates the criterion for his assertion in astrology’s vagueness which makes it escape falsification while Thagard locates his criterion in the practice of the community of astrologers. Nevertheless, both agree that astrology remains unprogressive and has little explanatory power. The two also differ in their motivations for providing a theory of demarcation. Thagard accuses Popper’s theory as anti-Marxist and anti-Freudian while Thagard’s motivation for presenting his criterion for demarcation is according to him due to the pressing issue of lack of public concern with the advancement of science. As more people become blinded by the popularity of pseudoscience, genuine science would remain to be side-stepped. However, Popper remains hopeful when he stated that “all—or very nearly all—scientific theories originate from myths, and that a myth may contain important anticipations of scientific theories (…) I thus felt that if a theory is found to be non-scientific, or ‘metaphysical’ (as we might say), it is not thereby found to be unimportant, or insignificant, or ‘meaningless’, or ‘nonsensical (Popper 4).’” Thus, Thagard seems to be stricter in setting the boundary while Popper still recognizes the potential of those theories or fields of study which are considered pseudoscientific. Thagard’s principle of demarcation is appealing but accepting his principle entails the acceptance of cultural relativism. The lack of alternative theories that would replace currently existing theories makes the latter scientific for the time-being. A problem would arise as isolated areas that have no means of acquainting their communities with alternative theories continue to hail their current theories as scientific, in contrast to those areas that have access to alternative theories. In my opinion, it is necessary and important for us to have a criteria for demarcating genuine science and pseudo-science for the purpose of convenience. I agree with Popper’s criteria since having a demarcation allows us to easily recognize the more credible theories which is of course the scientific ones. Also, I would like to focus on the potential of Popper’s theory of falsifiability. For me, falsification is a viable method for narrowing down theories. It helps us to generate theories having clear cut scope of where they can be applied. I also am in favor of Popper’s belief on what seems to be a hierarchical process of transcendence. What was once pseudoscientific may be a legitimate science if it passes the falsifiability test. Hence, having a principle of demarcation is not for the purpose of degrading other theories but merely to neutrally put them into classifications that would determine how the scientific community would treat them. Scientific ones would be put into the pedestal while the pseudoscientific ones, the developing theories, are subject to more rigorous studies. This does not mean however that I am dismissing Thagard’s assertions completely considering that his views implying cultural relativism indeed happen in reality. It remains a challenge for scientific communities to reach out to a wider audience when it comes into making their findings known to all. Another challenge for them is to be acquainted with various cultural norms which they could treat as sources of what could be incorporated into scientific methodologies. References Popper, Karl.
