As the revenue of the farmer is realized in raw produce, or in the value of raw produce, he is interested, as well as the landlord, in its high exchangeable value, but a low price of produce may be compensated to him by a great additional quantity.

The variation in the value of money, however great, makes no difference in the rate of profits.

By far the greatest part of those goods which are the objects of desire, are procured by labour and they may be multiplied, not in one country alone, but in many, almost without any assignable limit, if we are disposed to bestow the labour necessary to obtain them.

Again two manufacturers may employ the same amount of fixed, and the same amount of circulating capital; but the durability of their fixed capitals may be very unequal.

Labour, like all other things which are purchased and sold... has its natural and its market price.

It appears to me that one great cause of our difference in opinion on subjects which we often discuss is that you have always in mind the immediate and temporary effects of particular changes, whereas I put these effects quite aside, and fix my whole attention on the long-term effects that will result from them.

Whenever the current of money is forcibly stopped, and when money is prevented from settling at its just level, there are no limits to the possible variations of the exchange.
