The mind is an interesting concept, and one that we usually only associate with humans given our conscious knowledge of "being" and abstract thought. But all humans have an innate individuality, something that makes us unique to the billions of other humans out there. We develop a personality, which defines how we interact with others, handle situations and make decisions. In the argument of nature vs nurture, I believe nurture has a huge impact on our personality and mind. Our experiences shape us, and serve as the foundation for future decisions. But given the uniqueness of each human and the myriad of motivations that propel us into action, we can be unpredictable, impulsive, complex. But I do believe in the physical manifestation of the mind: chemical reactions in the brain create our ability to think, feel, react. I do not adhere to the idea of a soul because nobody can manifest their soul like we manifest our mind into thoughts, memories and feelings. We are not conscious of a soul, and our soul does not compel us to act (unless we call our conscience a soul, but I would consider our conscience part of our mind). So much to uncover and understand about the mind that thinking about it is almost an ethereal concept.
