<p> In every sort of project there are two things to consider: first, the absolute goodness of the project; in the second place, the facility of execution.</p>
+
+
<p> In the first respect it suffices that the project be acceptable and practicable in itself, that what is good in it be in the nature of the thing; here, for example, that the proposed education be suitable for man and well adapted to the human heart.</p>
+
+
<p> The second consideration depends on relations given in certain situations — relations accidental to the thing, which consequently are not necessary and admit of infinite variety.</p>
