Laws of Nature and Time’s Arrow
- 111 Downloads
Does time have an ‘arrow’ as Eddington  concluded from the second law of thermodynamics? Is temporal asymmetry a consequence of the differences between man’s ways of knowing the past and the future (Smart )? Is time ‘anisotropic’ (Mehlberg ), that is, intrinsically different depending upon its two opposite orientations (towards and away from the future), in contrast to spatial isotropy? Or should we rather inquire into whether time is unidirectional (Zilsel ) and therefore at variance with the bidirectionality of spatial lines? Is time irreversible since it never flows back (Margenau , p. 79ff)?
