Published posthumously in 1953, 'Philosophical Investigations' is a seminal work by Ludwig Wittgenstein that challenges many of the ideas presented in his earlier work, 'Tractatus Logico-Philosophicus'. The book is divided into two parts and consists of short observations or 'remarks' that delve into topics such as the theory of language, language games, meaning, symbols, concepts, and categories. Wittgenstein argues that the meaning of a word is derived from its use within the context of a language-game, rejecting the idea that words gain meaning by referencing objects or mental representations. He emphasizes the importance of understanding language as a tool for communication and social interaction, rather than as a system for representing objective reality[2][4][5].

Published in 1859, 'A Tale of Two Cities' by Charles Dickens is a historical novel that contrasts the lives in London and Paris during the late 18th century. The story revolves around characters such as Charles Darnay, Sydney Carton, and Lucie Manette, each dealing with love, sacrifice, and the profound societal changes brought about by the French Revolution. The novel critiques both the conditions leading up to the Revolution and the Revolution itself, highlighting themes of resurrection, sacrifice, and the potential for positive change. Dickens's vivid portrayal of the social disparities and political unrest of the era, along with his iconic opening lines, 'It was the best of times, it was the worst of times,' make the novel a compelling exploration of human resilience and societal issues[3][4][5].
Through the looking-glass
Lewis Carroll
In this sequel to 'Alice's Adventures in Wonderland', Alice climbs through a mirror and enters a world where everything is reversed, much like a reflection. Here, she finds herself in a land laid out like a giant chessboard, where she must navigate to the eighth rank to become a queen. Along her journey, she meets a variety of bizarre characters, including the Red Queen, the White Queen, Tweedledum and Tweedledee, and Humpty Dumpty. The story is filled with Carroll's signature nonsensical logic, word play, and imaginative world-building.
