Yet, to the extent that they had an idea of total interes seen the interest for speculation as being given by S (Y), since for them saving was essentia aberrant acquisition of capital products, with the outcome that total interest was equivaler up to pay as a character rather than as a balance condition. Keynes observes this view in Ch where he observes it present in the early works of Alfred Marshall yet adds that "the regula never expressed to-day in this unrefined structure".
