Essentialism is a philosophical theory that posits that certain entities possess inherent qualities or 'essences' that define their identity. This perspective suggests that these essential characteristics are fundamental to the nature of the entity, influencing how it interacts with the world and is perceived by others. In the context of education and personal development, essentialism emphasizes focusing on the most important aspects of life and learning, advocating for a disciplined approach to prioritize what truly matters. This approach encourages individuals to eliminate distractions and concentrate on their core values and goals.
