Ludwig Wittgenstein was an Austrian philosopher who inspired two significant philosophical movements of the 20th century — logical positivism and ordinary language philosophy. Though born into one of the wealthiest families in Vienna, he was deeply influenced by philosophy and pursued a career in the field, going against his father's wishes, who wanted Wittgenstein to join the family business. Wittgenstein was greatly influenced by prominent philosophers like Bertrand Russell and Gottlob Frege. He applied modern logic to metaphysics, providing a new understanding of the relationships between the world, thought, and language, thereby redefining the nature of philosophy. He was a highly sensitive and introverted person who often became annoyed or disturbed by things around him. Undoubtedly, he was one of the greatest philosophers of the 20th century and continues to influence contemporary philosophical thought in many areas, including logic and language, perception and intention, ethics and religion, aesthetics, and culture, among others.
