Now let us briefly review the fourth fundamental law of logic, according to which everything must have an adequate cause. This law is likewise very well worthy of attention, yet it is very inadequate, because the question what should be our conception of the world and what is the constitution of the most highly developed thinking faculty of the world requires the answer: the world, in which everything has its adequate cause, is nevertheless, including consciousness and the faculty of thought, without beginning, end, and cause, that is, a thing justified in itself and by itself. The law of the adequate cause applies only to pictures made by the human mind. In our logical pictures of the world everything must have its adequate cause. But the original, the universal cosmos, has no cause, it is its own cause and effect. To understand that all causes rest on the causeless is an important dialectic knowledge which first throws the requisite light on the law of the necessity of an adequate cause. Formally everything must have its cause. But really everything has not only one cause, but innumerable causes. Not alone father and mother are the cause of my existence, but also the grand parents and great grand parents, together with the air they breathed, the food they ate, the earth on which they walked, the sun which warmed the earth, etc. Not a thing, not a process, not a change is the adequate cause of another, but everything is rather caused by the universe which is absolute. When philosophy began its career with the intention of understanding the world, it soon discovered that this purpose could be accomplished only by special study. When it chose understanding, or the faculty of thought, as the special object of its study, it separated its specific object too far from the general existence. Its logic, in opposing thought to the rest of existence, forgot the interconnection of the opposites, forgot that thought is a form, a species, an individuality which belongs to the genus of existence, the same as fish to the genus of meat, night to the genus of day, art to nature, word to action, and death to life. It does not attempt to explore the essence of thought for its own sake, but for the purpose of discovering the rules of exploring and thinking correctly. It could not very well arrive at those coveted rules, so long as it idealized truth transcendentally and elevated it far above the phenomena. All phenomena of nature are true parts of truth. Even error and lies are not opposed to truth in that exaggerated sense in which the old style logic represents them, which teaches that two contradictory predicates must not be simultaneously applied to the same subject, that any one subject is either true or false, and that any third alternative is out of the question. Such statements are due to an entire misconception of truth. Truth is the absolute, universal sum of all existing things, of all phenomena of the past, present, and future.
