Now that the formal study of rhetoric has ceased to be a part of the higher education, the more strictly technical parts of Quintilian's work, like those of the _Rhetoric_ of Aristotle, have, in a great measure, lost their relevance to actual life, and with it their general interest to the world at large. Both the Greek and the Roman masterpiece are read now rather for their incidental observations upon human nature and the fundamental principles of art, than for instruction in a particular form of art which, in the course of time, has become obsolete. These observations, in Quintilian no less than in Aristotle, are often both luminous and profound, A collection of the memorable sentences of Quintilian, such as has been made by his modern editors, is full of sayings of deep wisdom and enduring value. _Nulla mansit ars qualis inventa est, nec intra initium stetit; Plerumque facilius est plus facere, quam idem; Nihil in studiis parvum est; Cito scribendo non fit ut bene scribatur, bene scribendo fit ut cito; Omnia nostra dum nascuntur placent, alioqui nec scriberentur_;--such sayings as these, expressed with admirable terseness and lucidity, are scattered all over the work, and have a value far beyond the limits of any single study. If they do not drop from Quintilian with the same curious negligence as they do from Aristotle (whose best things are nearly always said in a parenthesis), the advantage is not wholly with the Greek author; the more orderly and finished method of the Roman teacher marks a higher constructive literary power than that of Aristotle, whose singular genius made him indeed the prince of lecturers, but did not place him in the first rank of writers.
