It follows that the aggregate saving of the first individual and of others taken together must necessarily be equal to the amount of current new investment.

因此，第一个人和其他人的总储蓄必然等于当前新投资的数额。

Thus, after all, the actual rates of aggregate saving and spending do not depend on Precaution, Foresight, Calculation, Improvement, Independence, Enterprise, Pride or Avarice. Virtue and vice play no part.

因此，归根结底，总储蓄和支出的实际比率并不取决于预防、远见、计算、改进、独立、进取、骄傲或贪婪。美德和恶习无关紧要。

Moreover, as we shall see, the amount of the change in aggregate saving which results from a given change in the quantity of money is highly variable and depends on many other factors.

此外，正如我们将看到的，由给定的货币数量变化引起的总储蓄的变化量是高度可变的，并且取决于许多其他因素。

It is true that an unexpected increase of investment in a particular direction may cause an irregularity in the rate of aggregate saving and investment which would not have occurred if it had been sufficiently foreseen.

确实，特定方向的投资意外增加可能会导致总储蓄率和投资率的不规则性，如果能够充分预见这种情况就不会发生。
