Concerning such [dimensionless constants] I would like to state a theorem which at present cannot be based upon anything more than upon faith in the simplicity, i.e., intelligibility, of nature: there are no arbitrary constants of this kind; that is to say, nature is so constituted that it is possible logically to lay down such strongly determined laws that within these laws only rationally completely determined constants occur (not constants, therefore, whose numerical value could be changed without destroying the theory).

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "Concerning such [dimensionless constants] I would like to state a theorem which at present cannot be based upon anything more than upon faith in the simplicity, i.e., intelligibility, of nature: there are no arbitrary constants of this kind; that is to say, nature is so constituted that it is possible logically to lay down such strongly determined laws that within these laws only rationally completely determined constants occur (not constants, therefore, whose numerical value could be changed without destroying the theory)." in the context of "Albert Einstein, "Autobiographical Notes" (1949)" to mean that wisdom is timeless.
