Something to think about:<\/p>\n
The general perception is<\/a> that time flows or\u00a0moves<\/strong> \"from\" the past and \"to\" the future. It's not clear what this \"motion\" actually is<\/em>, though. At least, I think, we can all agree that \"the place memories represent\" is<\/em> the past (and the \"from\", if anything is,) and that \"the place plans represent\" is<\/em> the future (and the \"to\", if anything is).<\/p>\n Some hold<\/a> that \"causality\" isn't real. But it might be more accurate to say that \"causality\" is whatever it is that RCTs<\/abbr> measure<\/strong>. Mass and photons might not \"exist\", either, but we still refer to \"whatever causes gravity\" and \"whatever trips photon detectors\", after all\u2014and have a single word for each! Futher, I think that it is<\/em> nonsense to say that \"the future causes the past\" (outside of any causal loops proper<\/a>). Given that causality exists, and it's nonsensical for the future to \"cause\" the past, we could then establish that causality is also necessarily tied up with the \"direction\" of time.<\/p>\n The last question, then, would be: is entropy<\/strong> necessarily connected to causality? (I think this is likely, given the necessity<\/em> of entropy in an RCT<\/abbr>.) Perhaps a good next step to pulling on this thread would be Judea Pearl's writings.<\/p>\n
