SPECIMEN III
Build the argument
The argument built one step at a time, from premise to conclusion.
But this is no reason for denying that mental pleasure and pain may be much greater than physical pleasure and pain. For in the case of the body, all we can feel is what is actually now present. With the mind, both the past and future can affect us. To be sure, when we feel physical pain, we experience equal mental pain; but the pain can be hugely increased if we believe it is some eternal and infinite evil that is in store for us. The same point applies to pleasure: it is all the greater if we fear no such evil. Therefore the greatest mental pleasure or pain has more influence on our happiness than does physical pleasure or pain of equal duration.
Seven steps fit one column, so the map stays still. A much longer argument would let you zoom out to this overview and back.
