Final answer:
The author uses metaphor and personification in the given statement to convey the idea of ignoring painful truths and succumbing to temptation.
Step-by-step explanation:
The two rhetorical strategies that the author most clearly uses in the given statement are metaphor and personification.
The statement 'listen to the song of the siren till she transforms us into beasts' is a metaphor, comparing the allure of the siren's song to our tendency to ignore painful truths.
