for all things rhetorical try
silva rhetoricae.
(I can't remember these distinctions myself; I swear by this anonymous quote from a college classics department chairman, "The subtle distinction between two terms [of rhetoric] is completely irrelevant.")
Well, thanks all the same.
I do know that "paraleipsis" is usually in the dictionary, while "apophasis" is usually not. So maybe the latter is just a rare synonymn for the former. This assumption sometimes turns out to be false, but in this connexion, I absolutely (and paraleipsistically) refuse to mention "synecdoche" and "metonymy".
I've never had any problem distinguishing between synedoche and metonymy. I just never remember which is which.
Presumably you mean cataphasis rather than apophasis? ~ the differenc between affirmation and denial. I share the regular puzzlement over these niceties of rhetorical figures: the examples offered don't always seem to me to well illustrate what the speaker claims they do.
The pair of cataphasis and paralipsis I understand to be really just a mattter of degree of emphasis: cataphasis merely states whilst claiming not to so do ("I will refrain from mentioning my opponent's diminutive stature"), whilst paralipsis seems more ironic in tone ("it would be cruel to draw attention to my opponent's diminutive height, which clearly has no bearing on his wish for smaller doorways").
Fong's pair are a typical example of classifications that, not only do I not remember the difference, but even when I look 'em up again I can't see clear water between!
cataphasis: a kind of paralipsis in which one explicitly affirms the negative qualities that one then passes over.
apophasis: allusion to something by denying that it will be mentioned, as in I will not bring up my opponent's questionable financial dealings.
paraleipsis: pretended or apparent omission by which a speaker artfully pretends to pass by what he really mentions; as, for example, if an orator should say, I do not speak of my adversary's scandalous venality and rapacity, his brutal conduct...

Not according to the standard online definition, as linked by tsuwm:
apophasis (Gk, denial) The rejection of several reasons why a thing should or should not be done and affirming a single one, considered most valid.
So if you knew the answer, pray tell why did you ask the original question?
So, was Sherlock Holmes advocating an apophasisian method when he said to "Eliminate the impossible and whatever remains, no matter how unlikely, must be true." ?
