In the novel, the spice drug, also known as melange, takes on two different layers of significance: it represents valuable worldly resources that result in epic power plays, as well as the use of drugs to reach the human mind’s potential. Dune, a story set in a feudal society spread across the universe, is strongly focused on the clashes for control over the crop spice that is only mined from the planet Arrakis. Set twenty thousand years in the future, humanity has abolished all computers and thinking machines, and now relies on the mind-altering qualities of spice. Spice is a drug that can extend human life, allow interstellar space travel, and bestow heightened cognitive powers. Spice is therefore the most valuable commodity in the universe and has allowed humanity technological progress and cognitive development. As the most important resource in the galaxy, the spice drug symbolizes resources that have been critical for humanity’s technological and cultural advancements. Examples include digital data, as well as fossil fuels such as petroleum, coal, and natural gas. As with spice, political battles have constantly pivoted on control of these real-world resources. With Dune written in 1960s America, spice can also represent recreational drugs of the time such as marijuana, cocaine, and LSD; in many communities, it was popularly believed that such drugs could increase cognitive abilities by unlocking dormant parts of the human brain. Like spice, such drugs are also highly addictive and often require the user to take more and more to achieve the same effects.
Spice Quotes in Dune
People are the true strength of a Great House, Paul thought. And he remembered Hawat’s words: “Parting with people is a sadness; a place is only a place.”
The Guild Navigators, gifted with limited prescience, had made the fatal decision: they’d chosen always the clear, safe course that leads ever downward into stagnation.
“If I hear any more nonsense from either of you,” Paul said, “I’ll give the order that’ll destroy all spice production on Arrakis … forever.”
[…]
“Do it!” Paul barked. “The power to destroy a thing is the absolute control over it. You’ve agreed I have that power. We are not here to discuss or negotiate or compromise. You will obey my orders or suffer the immediate consequences!”
“He means it,” the shorter Guildsman said. And Paul saw the fear grip them.
