Who are we - the creators of our own destiny or a biomachine, each action of which is predetermined in advance? This question has been asked by humanity since time immemorial. Renowned neuroscientist Hannah Crichlow is trying to answer this question with her science, seeking help from specialists in various fields: from genetics and psychology to theology. In her research, Hannah describes how the brain develops and learns throughout life, which determines taste and sexuality preferences, love, friendship and shapes beliefs and moral and ethical ideas. This book will help you understand how, armed with the knowledge obtained by neuroscientists, you can change your own destiny.
