Consciousness often seems like something familiar, but once you start to think about it, a whole world of questions unfolds before you. In the lecture at the Mayakovsky Library, the discussion will revolve around how philosophy, psychology, and neuroscience explain our inner experience differently and why this topic continues to puzzle researchers. Consciousness accompanies us every second, but explaining what exactly we experience turns out to be surprisingly difficult. Philosophers debate the nature of subjective experience, psychologists study the patterns of perception and behavior, and neurophysiologists look at brain activity, trying to link the electrical activity of neurons with lived experiences. In the lecture at the Mayakovsky Library, these lines will be woven into a single narrative to show how different thinkers have described the same phenomenon. Listeners will learn what traits are typically attributed to consciousness: self-awareness, the ability to reflect, the experience of time, and freedom of choice. A separate section will be dedicated to how the understanding of human conscious life has historically emerged and what has changed in perceptions of it from antiquity to modern science. An important topic of discussion will be child development: when a child begins to recognize themselves, how the "I" is formed, and why this process is of interest to both philosophers and brain researchers. Other forms of sensitivity will not be overlooked either. The lecturer will raise the question of animal consciousness, discuss whether we can speak of an "inner world" in different species, and how our moral intuitions change when we acknowledge their complex experiences. Another narrative is related to artificial intelligence and modern technologies: can machines ever possess consciousness, or are we only dealing with behavior imitation? The starting point for the discussion will be current philosophical and interdisciplinary concepts that answer the question of what consciousness is and what role it plays in our lives in different ways.
