Okay how about this, I've included more textual reference and one rhetorical device, by which my next paragraph would be more rhetorical based.
My q was: "In your view, how have rhetorical techniques been used to reveal memorable ideas in the speeches set for study"
The value of context within a speech is immeasurable, in which the memorable ideas of a speech are amplified greatly with our appreciation of the background of each speaker and their address. Paul Keating's landmark 'Redfern Speech' was delivered a largely Aboriginal audience in Redfern and was a prolific movement by which it marked the first occasion an Australian political leader publicly acknowledged the past transgressions of colonial policy on the Indigenous. Keating's speech served as a harsh reminded of the past injustices committed by "us non-Aboriginal Australians", collectively challenging us as the audience to "extend the opportunity, care and dignity" to these people. The speech was incredibly important as it coincided with the Wik and Native Title legal disputes of the time, an opportunity Keating capitalised on to exhibit true leadership and provide a highly moral and principled stance on the contentious issue. As prime minister of the late nineties, he provided a national impetus to begin forging a national path to reconciliation evident as he implements inclusive language rigorously "we". By us as an audience understanding the political climate of Keating's era, it is overwhelmingly apparent that the speech was declared during a crucial time for Australia which sought to usher in a new age of reconciliation. It is through a deep comprehension of the speaker's context, that rhetorical devices are enabled to function and accentuate a speeches theme and message considerably for time to come.
Thanks for your help so far!
