1 Cicero, Academica I.xviii.
1 Richard Cox, the current Dean of Christ Church and Haddon's former tutor at Eton. Presumably Haddon was delivering this oration at his invitation.
5 Cicero calls learning pabulum animorum at Academicae Quaestiones cxxvii and cibum humanitatis at De Legibus II.xxvii.
7 Haddon is referring to Cicero, De Officiis I.xiv.14 and Aristotle's understanding of virtue in his Nicomahaen Ethics.
7 There is something seriously wrong with this sentence and it does not seem that the problem can be blamed on the printer. It begins with doctrina as its subject but ends with a series of plural verbs as if the subject were literae.
9 This contradicts what Plato wrote at Meno 87c - 89c.
9 In his De Finibus.
9 This is what Socrates is made to say in the course of Plato's Meno. Aristotle wrote about prudence in his Nicomachean Ethics and Cicero in Book I of his De Officiis.
All references to Socrates in this oration of course refer to Socrates as he appears as a speaker in Plato's dialogues.
11 De Amicitia liv.
13 The reference is of course to Plato's Phaedo (Haddon would have done better to speak of learning than of letters, Socrates was no bookworm).
16 A catalogue of the Greek philosophers Cicero mentions in his philosophical works.
16 The inmates of Christ Church have always referred to their college as "The House."
19 This individual seems impossible to identify. According to an understanding that Haddon got his Christian name wrong, someone might imagine that he was Henry Holbeach, appointed Bishop of Lincoln in 1547. But Holbeach was Cambridge-educated and so scarcely deserves the sobriquet Oxoniensis. Nor was there any Rector of Lincoln College, Oxford, having the Christian name John during the appropriate time-frame. Seemingly we must conclude that this man was a Canon at Lincoln cathedral or a Fellow of Lincoln College.
20 The college was originally founded by Wolsey under the name Cardinal College, and after Wolsey's downfall was refounded by Henry VIII. The assumption is that, as its founder, Henry has a special concern for the progress and welfare of its students.
