_“The progress of Science universally is retarded, because
sufficient attention is not paid to explaining essentials in
particular and exactly to define the terms employed.”--Euclid._

_“The first care of the sage should be to discover the true
character of his pupils. By his questions he should assist them
to explain their own ideas and by his answers he should compel
them to perceive their falsities. By accurate definitions he
should gradually dispel the incongruities in their earlier
education and by his subtlety in arousing their doubts, he should
redouble their curiosity and eagerness for information; for the
art of the instructor consists in inciting his pupils to that
point at which they cannot endure their manifest ignorance._
_“Many, unable to undergo this trial and confounded by offended
self-conceit and lacking the fortitude to sustain correction,
forsake their master, who should not be eager to recall them.
Others who learn from humiliation to distrust themselves should
no longer have snares spread for their vanity. The master should
speak to them neither with the severity of a censor nor with
the haughtiness of a sophist, nor deal in harsh reproaches nor
importunate complaints; his discourse should be the language of
reason and friendship in the mouth of experience.”--Socrates._
