Since molecules are inaccessible to immediate observation, our conception of the molecule is brought about by transdiction which entails invention of various transcendental ideas. In organic chemistry we think that molecules consist of atoms, bonds, functional groups, etc. This is, however, not the unique description of the molecule as is shown by quantum mechanical calculations, for example. Then, what description represents the real molecule? Before asking this question, we have to consider what the real molecule is in the first place. Constructive realism distinguishes our cognitive world and the world just given, and claims that we should accept the former as reality. Understanding our cognitive world is possible only through construction of micro-worlds. Atoms (in molecules), bonds, functional groups, etc., are micro-worlds which make sense in a theoretical framework of organic chemistry. In this study we translate a micro-world to an affordance and paraphrase it as a context-relative dispositional attribute of an {agent-world} complex. Then, we can understand that it is what we take as molecular structure, not what might be out there to be found, that we should accept as reality. Excluding metaphysical fictions from scientific arguments, constructive realism makes science a meaningful activity. Constructive realism claims that, for getting knowledge of the world, we have to integrate information into our own linguistic frame, i.e., to translate it. Strangification is a technique of intentionally taking an accepted proposition out of one scientific system and putting it into a completely different context. As is the case with translation, strangification brings about deeper understanding of philosophical as well as scientific grounds on which the proposition system holds. We apply this method to molecular structure and reveal that it is an ingenious model to describe molecular behavior in multi-molecular systems with strong interactions between molecules. Information provided by strangification is essential to claim the legitimacy of a proposition system. As far as strangification is properly applied, relativism is irrelevant to constructive realism.

理解分子结构需要建设性的现实主义

由于分子无法立即观察,因此我们对分子的概念是由转译带来的,转译需要发明各种先验思想。在有机化学中,我们认为分子由原子、键、官能团等组成。然而,这并不是量子力学计算所显示的分子的唯一描述。那么,什么描述代表了真正的分子呢?在问这个问题之前,我们必须首先考虑真正的分子是什么。建构现实主义将我们的认知世界和刚刚给定的世界区分开来,并主张我们应该接受前者为现实。只有通过构建微观世界,才能理解我们的认知世界。原子(在分子中)、键、官能团等,是在有机化学的理论框架中有意义的微观世界。在这项研究中,我们将微观世界转化为可供性,并将其解释为 {agent-world} 复合体的上下文相关倾向属性。然后,我们可以理解,我们应该接受的是我们认为是分子结构的东西,而不是可能在那里发现的东西。从科学论证中排除形而上学虚构,建设性现实主义使科学成为一项有意义的活动。建设性现实主义声称,为了获得关于世界的知识,我们必须将信息整合到我们自己的语言框架中,即翻译它。Strangification 是一种有意从一个科学系统中取出一个被接受的命题并将其放入一个完全不同的上下文中的技术。和翻译一样,异化带来对命题系统所依据的哲学和科学基础的更深入理解。我们将这种方法应用于分子结构,并揭示了它是一个巧妙的模型来描述分子之间具有强相互作用的多分子系统中的分子行为。由异化提供的信息对于主张命题系统的合法性至关重要。就适当地应用异化而言,相对主义与建设性现实主义无关。由异化提供的信息对于主张命题系统的合法性至关重要。就适当地应用异化而言,相对主义与建设性现实主义无关。由异化提供的信息对于主张命题系统的合法性至关重要。就适当地应用异化而言,相对主义与建设性现实主义无关。
