With this mindset, if we encounter something novel that doesnt exist or isn’t possible in 3d, instead of fighting with our brains we can simply say that a 4d universe allows such a possibility and in order to gain a 4d understanding which we have chosen to undertake we have to accept it.

wow so if I just say “it must be in 4d then” everytime i see something impossible in 3d I will slowly start thinking in 4d. thats amazing. /s
