Universality
Brahma Viharas (Divine abiding practices) of Buddhism:
metta (loving-kindness);

Applicability
When I started off my career in defended divorce cases I greatly admired the
smooth and elegant advocacy of Lord Salmon, who . . . seemed to me to win
his cases with all the noise and bluster of a perfectly tuned Rolls-Royce
coasting down hill. Cyril Salmon would take out his more valuable
possessions, his gold watch and chain, his heavy gold key-ring and cigarettelighter, and place them on the bench in front of him. Then he would . . .
plunge his hands deep into his trouser pockets and stroll negligently up and
down the front bench lobbing faultlessly accurate questions over his shoulder
at the witness-box. Here, I thought, was a style to imitate. For my early
cross-examinations I would . . . take off my battered Timex watch, lug out my
bundle of keys held together with a piece of frayed string and pace up and
down firing off what I hope were appropriate questions backwards. I
continued with this technique until an unsympathetic Judge said, ‘Do try and
keep still Mr Mortimer. It’s like watching ping-pong.’
John Mortimer, 1984, Clinging to the Wreckage, p. 96.

Status of Arguments
Must agent-based appraisal of argumentation commit the ad
hominem fallacy?
Ad Hominem Arguments
consist in bringing alleged facts about Jones to bear in an
attempt to influence hearers’ attitudes toward Jones’s
advocacy-of-P
Alan Brinton, 1995, ‘The ad hominem’, in Hansen & Pinto, Fallacies, p. 214.
But are all instances of ad hominem necessarily fallacious?

Virtues vs. Skills
An Aristotelian Distinction . . .
In the matter of arts and skills, they say, voluntary error is
preferable to involuntary error, while in the matter of virtues . . .
it is the reverse.
Philippa Foot, 1978, Virtues and Vices, p. 7.
. . . Applied to Argument
Virtue : Skill :: Sophism : Paralogism

The Virtues of Argument
Summary
Virtue theory is a potentially fruitful methodology for
informal logic;
Addresses recurring problems at least as satisfactorily as
other virtue theories;
Exploits under-utilized virtue/skill distinction.
Future work:
Analyses of individual virtues;
Systematic basis for appeals to moral obligations in
reasoning.
