That I conceive would be nearest to perfection—the binary scale, with means to enable us to use decimal multiples or sub-multiples" He also stated: "For daily life, people understand sub-division by halves better than any other sub-division," and "the law is universal that a binary sub-division is easier than anything else."
Professor De Morgan claimed that "Binary sub-division must always be used by the common people
