Character Analysis
Silver Tongued Devil
Alfred Doolittle is a smooth-talking garbage man, a serial monogamist (although he's not always really married), a drunk, and a deadbeat dad. He's got a lot to say about "middle class morality" and complicated theories about the deserving and undeserving poor.
In other words, he's kind of like Henry Higgins: a philosophizing scuzzball that we somehow enjoy watching.
Alfred Doolittle has principles, but they're not exactly conventional: he has no trouble milking five pounds from Higgins, but he doesn't want anymore than that. He wants just enough money to have a few drinks and some fun.
In order to understand Doolittle, you have to understand how he speaks. This exchange is notable:
DOOLITTLE ["most musical, most melancholy"] I'll tell you, Governor, if you'll only let me get a word in. I'm willing to tell you. I'm wanting to tell you. I'm waiting to tell you.
HIGGINS. Pickering: this chap has a certain natural gift of rhetoric. Observe the rhythm of his native woodnotes wild. "I'm willing to tell you: I'm wanting to tell you: I'm waiting to tell you." Sentimental rhetoric! That's the Welsh strain in him. It also accounts for his mendacity and dishonesty. (2.232-3)
He is the sum of his mysterious speaking ability. You can describe what Doolittle's saying with all sorts of fancy Greek words, but it's enough to note how he repeats those three phrases that Higgins singles out, and how his speech is sort of singsong-y.
The Trouble With Success
Whether or not we believe what Doolittle's talking about doesn't matter, it sounds nice. These skills get Doolittle into trouble when Higgins nominates him for some such speaking position…and he gets it, along with a generous income. He can't handle all the money; he doesn't want to be "touched" (asked to spare some change) in the same way he "touched" Higgins.
Doolittle demonstrates how powerful and potentially dangerous words can be. Lucky for us, his intentions are (mostly) honorable. He's the character most prone to lecturing—yes, even more so than Higgins—and though his theories may not be entirely logical, his little sermons do raise some issues regarding class relations.
Think of him this way: he's a stereotype of a bombastic barfly…with an oratorical twist.
