what stimulates consicous thought ?

Consciousness is a term that refers to the relationship between the mind and the world with which it interacts.^[1] It has been defined as: subjectivity, awareness, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive control system of the mind.^[2] Despite the difficulty in definition, many philosophers believe that there is a broadly shared underlying intuition about what consciousness is.^[3] As Max Velmans and Susan Schneider wrote in The Blackwell Companion to Consciousness: "Anything that we are aware of at a given moment forms part of our consciousness, making conscious experience at once the most familiar and most mysterious aspect of our lives."^[4]
