Every notable advance in technique or organization has to be paid for, and in most cases the debit is more or less equivalent to the credit. Except of course when it's more than equivalent, as it has been with universal education, for example, or wireless, or these damned aeroplanes. In which case, of course, your progress is a step backwards and downwards.
While we cannot describe its appearance (the equivalent), we can define its function. When a photograph functions as an Equivalent we can say that at that moment, and for that person the photograph acts as a symbol or plays the role of a metaphor for something that is beyond the subject photographed.
One hears of the mechanical equivalent of heat. What we now need to discover in the social realm is the moral equivalent of war: something heroic that will speak to men as universally as war does, and yet will be as compatible with their spiritual selves as war has proved itself to be incompatible.
Observation over many years has taught us that the chief losses to investors come from the purchase of low-quality securities at times of good business conditions. The purchasers view the good current earnings as equivalent to 'earning power' and assume that prosperity is equivalent to safety.
There are no forms in nature. Nature is a vast, chaotic collection of shapes. You as an artist create configurations out of chaos. You make a formal statement where there was none to begin with. All art is a combination of an external event and an internal event... I make a photograph to give you the equivalent of what I felt. Equivalent is still the best word.
In the kingdom of ends everything has either a price or a dignity. Whatever has a price can be replaced by something else as its equivalent; on the other hand, whatever is above all price, and therefore admits of no equivalent, has a dignity. But that which constitutes the condition under which alone something can be an end in itself does not have mere relative worth, i.e., price, but an intrinsic worth, i.e., a dignity.
Unruly beings are as unlimited as space They cannot possibly all be overcome, But if I overcome thoughts of anger alone This will be equivalent to vanquishing all foes. Where would I possibly find enough leather With which to cover the surface of the earth? But (wearing) leather just on the soles of my shoes Is equivalent to covering the earth with it. Likewise it is not possible for me To restrain the external course of things; But should I restrain this mind of mine What would be the need to restrain all else?
Those who commit these types of scandals are guility of the spiritual equivalent of murder, but I, here among you to prevent something far worst for you. While those who give scandal are guilty of the spiritual equivalent of murder, those who take scandal- who allow scandals to destroy faith- are guilty of spiritual suicide.
Saint Francis de Sales
Like gold, U.S. dollars have value only to the extent that they are strictly limited in supply. But the U.S. government has a technology, called a printing press (or, today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at essentially no cost. By increasing the number of U.S. dollars in circulation, or even by credibly threatening to do so, the U.S. government can also reduce the value of a dollar in terms of goods and services, which is equivalent to raising the prices in dollars of those goods and services.
