Human freedomFreedom in the mind, freedom in nature and freedom in the subjectivity of the individual are three types of freedom. However, freedom should be expressed within the limits of reason and morality. Having freedom is equivalent to having the power to think, speak and act without restrictions imposed from outside. Finding freedom to live free, in fact, is the idea common to Plato with "The Allegory of the Cave"; Henry David Thoreau with "Where I Lived and What I Lived For"; and Jean Paul Sartre with "Existentialism". In general, Plato, Thoreau, and Sartre suggested that human life should be free. They differ in what that freedom is. Plato thinks it is found in the world of the intellect, Thoreau thinks freedom is found in nature, and Sartre thinks freedom is found in the subjectivity of the individual. Plato finds freedom in the world of the intellect.

They had different views on freedom, but combining Plato's freedom in mind, Thoreau's freedom in nature, and Sartre's freedom in the subjectivity of the individual gives people a clear and perfect image of freedom. Understanding freedom is the first step to finding freedom in real life. So, in this specific case, college students have the freedom to think critically. Students' freedom is to be able to study what they want and discover their own path towards a bright future. However, how to use freedom correctly is the difficult question for students in real life.
