Niels Bohr's interpretation of quantum mechanics is often cast as positivist and sometimes explicitly claimed to be influenced by logical positivists due to some similarities in their thinking. While it is certainly the case that some logical positivists attempted to recruit Bohr, this paper argues that Bohr had interests of his own in the logical positivists.

Bohr's interpretation of quantum mechanics focuses on observation, the use of classical concepts in quantum mechanics, and indeterminacy of quantum processes as opposed to uncertainty of measurement. His view thereby shares some common ground with the logical positivists' views on verification, the observation language, and anti-metaphysics. But Bohr also emphasized complementarity: that certain pairs of concepts – such as position and momentum – are mutually exclusive in quantum mechanics since they, according to Bohr, are only meaningful relative to different experimental arrangements.

Bohr believed that complementary brought a general epistemological lesson for all of science that an objective description of nature is not separable from the observational and experimental conditions under which we explore nature. Motivated by the common ground between himself and logical positivism, Bohr tried to persuade the logical positivists and Carnap in particular to adopt and champion complementarity as well as part of their unity of science program. Though his efforts ultimately proved in vain, Bohr's attempts to influence logical positivism disprove the claim that his engagement with them was reluctant and purposefully limited.

玻尔希望卡尔纳普从量子力学中学到什么

尼尔斯·玻尔对量子力学的解释经常被认为是实证主义的,有时由于他们的思想有一些相似之处而明确声称受到逻辑实证主义的影响。虽然某些逻辑实证主义者确实试图招募玻尔,但本文认为玻尔对逻辑实证主义者有自己的兴趣。

玻尔对量子力学的解释侧重于观察、量子力学中经典概念的使用以及量子过程的不确定性,而不是测量的不确定性。因此,他的观点与逻辑实证主义者关于验证、观察语言和反形而上学的观点有一些共同点。但玻尔也强调了互补性:某些概念对——例如位置和动量——在量子力学中是相互排斥的,因为根据玻尔的说法,它们仅相对于不同的实验安排才有意义。

玻尔认为,互补性为所有科学带来了一个普遍的认识论教训,即对自然的客观描述与我们探索自然的观察和实验条件是分不开的。在他自己和逻辑实证主义之间的共同点的推动下,玻尔试图说服逻辑实证主义者,特别是卡尔纳普,采用并支持互补性以及他们的科学统一计划的一部分。尽管他的努力最终被证明是徒劳的,但玻尔试图影响逻辑实证主义的尝试反驳了他与他们的接触是不情愿和故意限制的说法。
