Presence, or existence, refers to the state of being real or having an actual presence in the world. It encompasses everything that can be perceived, whether through the senses or through thought. This includes physical objects like trees, animals, and buildings, as well as abstract concepts like ideas and emotions. In philosophy, the concept of presence is often explored in relation to consciousness and awareness. It raises questions about what it means to exist and how we understand our own existence in relation to others. The study of presence can lead to deeper insights into the nature of reality and our place within it.
