摘要

生物学领域内的物理学方法论视角创造了生物物理学的跨学科领域:一个探索强涌现思想的富有成效的领域。涌现实体的例子包括:细胞膜内的蛋白质组装，细胞外部信号的基因表达，DNA和拓扑异构酶的拓扑相互作用。信息流(本身由约束决定)被敦促作为向下因果关系的指示。强突现结构在高水平(更大规模)上携带信息，而这些信息不是由低水平(更小规模)上的信息总和构成的。生物物理学将经验的光芒投射到向下因果关系的形而上学问题上，而不必触及额外的复杂性和有争议的精神品质。114 t.c.b.麦克利什

Strong emergence and downward causation in biological physics

The methodological lens of physics within the realm of biology creates the interdisciplinary field of Biological Physics: a fruitful one with which to explore the idea of Strong Emergence. Examples of emergent entities are found in: e.g. protein assembly within cell membranes, gene expression from external cell signalling, topological interaction of DNA and topoisomerase enzymes. The flow of information (itself determined by constraints) is urged as an indicator for downward causation. Strongly emergent structures carry information at high (larger scale) level that is not constituted by the sum of information at low (smaller scale) levels. Biological physics throws empirical light on the metaphysical question of downward causation without having to broach the additional complexities and contested qualities of the mental. 114 T. C. B.
