The simplicities of natural laws arise through the complexities of the language we use for their expression.
Eugene WignerWhen the province of physical theory was extended to encompass microscopic phenomena through the creation of quantum mechanics, the concept of consciousness came to the fore again. It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.
Eugene Wigner[T]he laws of quantum mechanics itself cannot be formulated ... without recourse to the concept of consciousness.
Eugene Wigner... mathematics is the science of skillful operations with concepts and rules invented just for this purpose.
