In several instances Senior improved the forms in which accepted doctrines were habitually stated. He also did excellent service by pointing out the arbitrary novelties, and frequent inconsistencies of terminology which were to be found in Ricardo's principal works. For example, Senior objected to Ricardo’s use of value in relation to the cost of production, and of high and low wages in correlation with a certain proportion of the product as distinguished from an absolute amount, as well as criticizing his peculiar employment of the epithets "fixed" and "circulating" as applied to capital. Senior also revealed that in numerous instances the premises assumed by Ricardo were false.
