Reply to comment by WrongAspects in Physicist Max Planck on Idealism and the Role of Faith in Science by owlthatissuperb

Curious if you can provide any quotes/etc that back up your claims about Penrose saying "nothing exists outside of time and there is no such thing as outside of time."

Penrose is frequently described as a Platonist [1] [2] [3] [4]. The opening paragraph on Platonism from the Stanford Encyclopedia of Philosophy [5] says:

> Platonism is the view that there exist such things as abstract objects — where an abstract object is an object that does not exist in space or time and which is therefore entirely non-physical and non-mental.

I find this diagram really useful for thinking about Penrose's picture of reality.

His views of time and the cyclic universe are well documented and he himself has described them numerous times in interviews found on the web.

I have never heard him describe himself as a platonist and even he was it doesn’t mean he accepts as a religion which demands strict obedience to some written dogma. He obviously believes in abstract mathematics and obviously believes mathematics can accurately reflect and describe reality. Some people may call that Platonism. Having said that I get the feeling platonists want to claim he is because it will afford their theory some prestige to be accepted by a famous scientist.

Penrose is first and foremost a scientist. He has a bedrock belief in empiricism and the importance of strict observation conducted using the scientific method.
