Meaning

Voltaire is urging every person to exercise independent judgment rather than simply accepting the ideas handed to them by authority, tradition, or social pressure. The second half of the thought is equally important: genuine intellectual freedom is not a private privilege but a right that belongs to everyone. True free-thinkers, in other words, do not hoard the liberty they claim for themselves.

Context

Voltaire spent much of his career challenging the religious and political orthodoxies of eighteenth-century France, and this line captures the spirit that ran through his essays, letters, and satirical works. He lived during the Enlightenment, a period when reason and individual conscience were being asserted against centuries of institutional authority. The idea that freedom of thought must be universal, not selective, was genuinely radical in an era when censorship and persecution of heterodox views were common instruments of power.

About the author

Voltaire was the pen name of the French writer and philosopher Francois-Marie Arouet, who lived from 1694 to 1778. He was one of the central figures of the European Enlightenment and produced an enormous body of work spanning satire, history, poetry, and philosophy. He was imprisoned in the Bastille and spent periods in exile, experiences that deepened his commitment to civil liberties and his distrust of unchecked authority. His wit and moral seriousness continue to make him one of the most widely read writers of his era.
