I once heard a man refer to his income as limited, in order to illustrate the hardship of a class of men, of which he of course was one, in having to pay a somewhat high income-tax. It is obvious that this man spoke enviously, and consequently admitted the existence of more fortunately placed individuals who had unlimited incomes. A little reflection would have shown the man that he was not taking up a paradoxical attitude. A "paradoxical attitude" is of course the assertion of one or more propositions of which the truth cannot be perceived by a philosopher--and particularly an idealist--and can be perceived by a logician and occasionally, but not always, by a man of common-sense. Such propositions are: "The cat is hungry," "Columbus discovered America," and "A thing which is always at rest may move from the position A to the different position B." Now, if a man had an unlimited income, it is an immediate inference that, however low income-tax might be, he would have to pay annually to the Exchequer of his nation a sum equal in value to his whole income. Further, if his income was derived from a capital invested at a finite rate of interest (as is usual), the annual payments of income-tax would each be equal in value to the man's whole capital. If, then, the man with an unlimited income chose to be discontented, he would be sure of a sympathetic audience among philosophers and business acquaintances; but discontent could not last long, for the thought of the difficulties he was putting in the way of the Chancellor of the Exchequer, who would find the drawing up of his budget most puzzling, would be amusing. Again, the discovery that, after paying an infinite income-tax, the income would be quite undiminished, would obviously afford satisfaction, though perhaps the satisfaction might be mixed with a slight uneasiness as to any action the Commissioners of Income-Tax might take in view of this fact.
