1/12 A thread on whether perception is discrete, an idea Varela, Rosch & I discussed in The Embodied Mind (72-79) and I covered in Waking, Dreaming, Being (40-45). I blogged about this at @philofbrains a while agohttp://philosophyofbrains.com/2015/07/29/is-consciousness-a-stream.aspx …

6/12 VanRullen and Koch restated the idea in their 2003 paper but stated it had been difficult to replicate Varela's findingshttps://www.cell.com/trends/cognitive-sciences/fulltext/S1364-6613(03)00095-0 …

10/12 Now, finally, for what set off this thread: I just read an excellent and comprehensive critical review of the discrete perception idea. White reviews evidence pro and con and raises difficult questions for the ideahttps://www.sciencedirect.com/science/article/abs/pii/S1053810018300047?via%3Dihub …

11/12 TLDR there's increasing evidence for periodic modulation of perceptual content based on endogenous neural rhythms. But it's not so clear this evidence supports discrete temporal perceptual frames (see White's review)

12/12 Coda: William James was right: consciousness flows, but it's not a uniform flow; it has inner rhythms. Whether it's also discrete (as Abhidharmikas held) is an open question
