Benedict de Spinoza argued that true freedom is found in the life of reason, where an individual acts according to the dictates of their own nature and moral understanding. By following the moral law, which is derived from reason, one escapes the bondage of passions and external compulsions. While other philosophers also discuss moral liberty, Spinoza is frequently cited for this specific rationalist interpretation of freedom as living in accordance with reason.

Postmodernism is a broad intellectual movement that challenges grand narratives and objective truths. It incorporates deconstruction, which analyzes the instability of language; post-structuralism, which examines how power structures shape meaning; and institutional critique, which questions the neutrality of cultural and political institutions. These approaches collectively emphasize the subjective, fragmented, and socially constructed nature of reality.

Walter Truett Anderson's analysis of postmodernism suggests that it is not a monolithic concept but rather a collection of diverse worldviews. He categorized these into several types, including the postmodern-ironist, scientific-rational, and social-traditional perspectives. By identifying these distinct frameworks, Anderson illustrated how postmodern thought interacts with and critiques various established ways of understanding reality, society, and human knowledge.

Walter Lippmann published 'An Inquiry into the Principles of the Good Society' in 1937. In this influential book, he critiques the rise of totalitarianism and collectivism, advocating for a form of liberalism that balances individual freedom with the necessity of a stable, rule-based social order in the modern industrial age.

The term 'postmodern' was first recorded in the 1870s, initially appearing in artistic and literary critiques. While its modern political and philosophical usage became prominent in the late 20th century, its etymological roots trace back to this earlier period. This term signifies a departure from the established norms of the modernist era, reflecting changing societal perceptions and the questioning of grand narratives.

Gayatri Chakravorty Spivak, a prominent postcolonial theorist, developed the concept of 'Strategic Essentialism.' This refers to the temporary, tactical use of an essentialist label or identity by marginalized groups to achieve specific political goals, despite acknowledging that such identities are socially constructed and inherently fluid.

Jawaharlal Nehru was a strong proponent of scientific humanism, a philosophy that integrates the rational, empirical methods of science with the ethical values of humanism. He believed that India's progress depended on adopting a scientific temper to overcome superstition and social backwardness, while simultaneously upholding democratic and humanitarian principles to ensure social justice and national development.

Bertrand Russell consistently argued that private property was a divisive force in society, leading to class conflict and inequality. He believed that the institution was rooted in historical violence and theft, and that it fundamentally undermined social cohesion. Therefore, the suggestion that he viewed private property as a factor that helped in the unity of the community is diametrically opposed to his well-documented philosophical stance on the subject.

Jeremy Waldron is noted for his critique of cultural essentialism, arguing instead for a cosmopolitan view where individuals exist in a 'hybrid' state, drawing from various cultural sources. He challenges the idea that individuals must belong to a single, bounded culture, suggesting that modern identity is fluid and constructed from a global pool of cultural resources.

James Tully is well-known for his work on constitutionalism and pluralism. He argues for a form of 'ancient constitutionalism' that recognizes the diverse cultural and political identities within a society, moving away from the rigid, monolithic structures often associated with modern nation-states to embrace a more inclusive, dialogical approach to governance.
