[filed under theme 26. Natural Theory / D. Laws of Nature / 4. Regularities / b. Best system theory ]

Full Idea

Lewis's simplicity and strength criteria introduce an element of subjectivity into the laws, because the best system seems to be determined by what we take to be simple and strong in a system.
