Halloween hasn't always been such a commercial affair. Historically, All Hallows' Eve marked the one day every year when people thought the worlds of the living and the dead overlapped. The holiday evoked a sense of mystery, intrigue, respect and fear. Today, it's rife with candy consumption and elaborate costumes. Here are seven quotes to celebrate Halloween in all its original glory.

1. “Be silent in that solitude,
Which is not loneliness—for then
The spirits of the dead, who stood
In life before thee, are again
In death around thee, and their will
Shall overshadow thee; be still.”

—From the poem “Spirits of the Dead,” by Edgar Allan Poe

2. "Double, double toil and trouble; Fire burn and cauldron bubble."

-- From the play "Macbeth," by William Shakespeare

3. "So from the world of spirits there descends
A bridge of light, connecting it with this,
O’er whose unsteady floor, that sways and bends,
Wander our thoughts above the dark abyss."

-- From the poem “Haunted Houses,” by Henry Wadsworth Longfellow

4. "We have no fear of you, silent shadows, who tread
The leaf-bestrewn paths, the dew-wet lawns. Draw near
To the glowing fire, the empty chair,—we shall not fear,
Being but ghosts for the lack of you, ghosts of our well-beloved dead."

-- From the poem “Hallow-E’en,” by Winifred M. Letts

5. "Halloween was confusing. All my life my parents said, 'Never take candy from strangers.' And then they dressed me up and said, 'Go beg for it.' I didn’t know what to do! I’d knock on people’s doors and go, 'Trick or treat.' 'No thank you.' " -- Rita Rudner, comedian

6. "Die, my dear? Why that’s the last thing I’ll do!" -- Groucho Marx

7. "I hate Halloween. I hate dressing up. I hate -- I wear wigs, makeup, costumes every day. Halloween is, like, my least favorite holiday." -- Amy Poehler, actor and comedian
