论科学假说形成的逻辑操作

Logical Operation of Scientific Hypothesis Generation

摘要:

科学假说形成的逻辑分为溯因推理和最佳说明推理两个阶段。人脑形成科学假说是通过搜索和提取、类比和组合、评价和选择三种逻辑操作。通过塞麦尔维斯产褥热病原的发现过程,结合大脑形成科学假说的逻辑操作,建构出科学假说形成的逻辑操作模型。该模型操作步骤为：面对异常现象,科学家通过搜索和提取、类比和组合创造出与异常现象相似的经验或模型,并借助相似经验现象的因果解释形成科学假说,再通过评价和选择得出最佳的科学假说。

Abstract:

Logic of Science hypotheses Generation can be divided into two stages : abductive reasoning and inference to the best explanation.The human brain form scientific hypothesis is through three logical operations:search and extraction,analogy and combination, selection and evaluation.According to Semmelweis’Discovery of puerperal fever pathogen, we construct mode of logical operations of Science hypotheses Generation.
