We all use thoughts without being aware of where they come from. They are simply there, coming to mind and touching us. But how? What are thoughts really, and where do they originate? How do thoughts connect to form chains of thought? Ideas, structures of thought, and bodies of knowledge: what supports them? They consist of vast complexes of information, a far-reaching web of interconnected and intertwined thoughts. What holds them together, what forces bind them? What gives them relevance, meaning, and significance? Is there perhaps an expiration date, a temporal decay for them? The author takes you on an exciting journey deep into the world of the microcosm with astonishing insights into the emergence of thoughts, what evokes them, and how they are shaped, captured, and evaluated. A journey into the human experience as well.
