When in the mind of man appetites and aversions, hopes and fears, concerning one and the same thing arise alternately, and diverse good and evil consequences of the doing or omitting the thing propounded come successively into our thoughts, so that sometimes we have an appetite to it, sometimes an aversion from it, sometimes hope to be able to do it, sometimes despair or fear to attempt it, the whole sum of desires, aversions, hopes and fears, continued till the thing be either done or thought impossible, is that we call Deliberation. (33)
