There can never be too many logicians. More than 2,000 years ago, Aristotle first described certain forms of thought. Based on his works, the so-called formal logic was later compiled, which is generally accepted today. About 200 years ago, Wilhelm Hegel created a complete version of logic and thereby made it a full-fledged science - the “Science of Logic”. However, he presented it in such a difficult-to-understand language that the entire content continues to remain poorly understood to this day. The book offered to the reader’s attention is an attempt to present Hegel’s logic in a concise and accessible form.
