Go Ask Alice is a reference to a Jefferson Airplane song called "White Rabbit," which alludes to rampant hallucinogenic drug use in Lewis Carroll's Alice in Wonderland. Did we lose you? Okay, let's start from the beginning.
Some people maintain that Alice in Wonderland can only have been written by an author with considerable hallucinogenic mushroom experience under their belt. After all, where else could Carroll get the idea about eating a mushroom to get bigger and smaller—and the whole Walrus and the Carpenter thing? That guy had to have been wasted, right? Maybe, and maybe not. Others contend that he merely had a fascination with all the right subjects that would have led him to explore the well-documented research on those who had accidentally taken hallucinogenic mushrooms.
Either way, people in the counterculture movement of the 1960s were fascinated by how well Carroll's epic tale of bizarre occurrences aligned with their far-out trippy experiences, and thus the two became inextricably connected. Jefferson Airplane liked this idea, so they wrote the song about lame-o parents and just how to "feed your mind." Here are some of the lyrics:
One pill makes you larger
And one pill makes you small
And the ones that mother gives you
Don't do anything at all
Go ask Alice
When she's ten feet tall
And if you go chasing rabbits
And you know you're going to fall
Tell them a hookah-smoking caterpillar
Has given you the call
Call Alice when she was just small
When the men on the chess board
Get up and tell you where to go
And you just had some kind of mushroom
And your mind is moving slowGo ask Alice
I think she'll know
Knowing this, then, it is important to note that the "author" of the diary is not Alice. She is referred to by that name out of popular misconception as well as convenience, but technically her name is never given.
