![]() One’s interpretation of the core concept of Pragmatism-i.e., questions at the structural level like “which paradigms are legitimate”-can easily be wrong: there is a “correct” or “ideal” set of structures/interpretations, and one’s interpretation is unlikely to perfectly match that.Ultimately, don’t get too lost in the analogy the main reasons to frame it this way are to emphasize that: The foundation can be pictured as a large slab of concrete on a plot of land, representing the broad statement “whatever approach or decision makes debate better is what should be preferred.” In contrast, your interpretations of “what approach or decision makes debate better” (which might include paradigms like Rule-ism and judging habits like flow-purism) are like structures (e.g., buildings, trees) that you can adapt and mold to fit on the foundation: you might suppose Resolutionism is an important structure but still carve a few exceptions into it to deal with the issues I mentioned in the previous article. No analogy is perfect, but it may be helpful to conceive of Pragmatism in two parts: the foundation and the structures. At the same time, Pragmatism at its generic core is incredibly bare, with almost no inherent structure: all it says is “whatever approach or decision (e.g., judging paradigm, theory, rule interpretation, definition) makes debate better is what should be preferred.” This is in contrast with something like Rule-ism and/or Resolutionism, which when taken wholesale explicitly dictate that an approach or decision should be preferred insofar as it is derived from the rules and/or how it relates to the veracity of the resolution. The result is that Pragmatism can bring together various concepts which, when taken alone and in their entirety, may not have clear connections with each other (or may even contradict each other). One of the best characteristics of Pragmatism is that it is a rather inclusive paradigm, while still being squarely framed around the criterion/concept of “whatever makes debate better.” That is to say, Pragmatism does not necessarily exclude a lot of the intuition or reasoning behind valuable paradigms/mindsets like Resolutionism and flow-purism. This article will also begin introducing the discussion on usage, although that will be covered primarily in the next article. Although I already briefly introduced the driving idea of Pragmatism, I will devote this article to explaining in more detail what Pragmatism is-and what it isn’t. ResultsĪre found to be remarkably stable against resolution.In the previous article in this series, I discussed some of the flaws with paradigms that rigidly rely on things such as traditions/norms and rules as the foundational metric for good theory arguments, judging philosophies, or other choices in debate (e.g., which definitions to prefer). (2010) at a 3 sigma level, thus indicating that our stellar disksĪre still too massive for the Dark Matter halo in which they reside. However, the baryonĬonversion efficiencies in our simulations differ from the relation given by Stars kinematicallyīelonging to the bulge form early, while disk stars show a clear inside-outįormation pattern and mostly form after redshift z=2. Gas is found to dominate at the centre of galaxies, with star formation ratesįollowing the observed Schmidt-Kennicutt relation. Gas profiles are relatively flat, molecular \approx 0.2), extended stellar and gas disks, flat rotation curves and We obtain spiral galaxies with small bulge-over-total stellar mass ratios (B/T (2-3) * 10^ Msun, both available at several resolution levels.
