What does this quote mean?

“To define is to limit.”

Definitions clarify ideas but can also narrow them, especially when a label is treated as the complete reality of a person or experience.

Source note: The Picture of Dorian Gray, 1891 edition, Chapter 17; Lord Henry answers the Duchess of Monmouth’s question “What are you?” with “To define is to limit.”

“To be, or not to be: that is the question.”

The line condenses an existential dilemma into a question about endurance, action, fear, and the unknown consequences of death.

Source note: Act 3, Scene 1; Hamlet weighs existence against suffering and uncertainty.

“Nature always wears the colors of the spirit.”

The same surroundings can feel different according to the observer’s inner state, linking perception of nature with emotion and perspective.

“The world is a perpetual caricature of itself.”

Social appearances repeatedly exaggerate or contradict reality, making ordinary life look like an ongoing parody of its own pretensions.

Source note: Soliloquies in England, “Dickens”; Santayana uses caricature to describe the gap between living reality and conventional masks.

“There is nothing either good or bad, but thinking makes it so.”

The line separates events from the judgments people place on them, a useful distinction for thinking about perception and response.

Source note: Hamlet, Act 2, Scene 2; Hamlet says this to Rosencrantz and Guildenstern while explaining that Denmark feels like a prison to him. The line is dramatic dialogue, not a detached psychological proposition by Shakespeare.

“All the world’s a stage, and all the men and women merely players.”

The metaphor treats life as a sequence of roles and stages, inviting reflection on identity, aging, and impermanence.
