Life and Matter: A Criticism of Professor Haeckel's "Riddle of the Universe"

This book aims to clarify the relationship between the mind and matter and refutes the two commonly held misconceptions. First, the belief that material energy cannot be guided or controlled, despite being constant in quantity, because of the transformations and transfers that occur on Earth. And second, the idea that life, as a specific guiding power, is simply one form of material energy, and that when it separates from matter, it will be replaced by other forms of energy. The book also serves as a counterargument to the speculative and destructive aspects of Professor Haeckel's popular book. However, it can be seen as a supplement, rather than a criticism, as it expands upon the scientific elements of Professor Haeckel's work and delves into more productive areas of inquiry.
