Metaphysical or transcendental truth , known as the order that reigns in the variety of different things, both simultaneous and successive, which are suitable for all beings. See the article on Order, where we explain that what distinguishes waking hours from sleeping is the order that reigns in the true and actual events of the day; whereas dreams create combinations in which there is neither truth nor reality, because they are deprived of sufficient reason and even assume the coexistence of contradictory things. The truth that results from order and almost coincides with it is thus suitable for every being, for God, the world, in the sense that it is regarded as a unit, and suitable for every individual existing in the world, man, tree, etc.

Thus, every being is true. This truth is intrinsic to being, and does not depend at all on our knowledge. It is different from logic, where we call things true when they seem so to us. When I say, for example, that here is an ingot of real gold, the truth is verified only if this ingot is really what I say it is; but this truth is one of judgment rather than of the being itself. The ingot is not as you say, but it has nonetheless transcendental truth , it is a real mass that cannot be anything other than what it is, and whose essence and attributes are linked by sufficient reason.

The two main principles, one of contradiction, the other of sufficient reason, are the source of this universal truth , without which there would be no logical truth in universal propositions, and singular propositions would only be true in the moment: because if a being is not so much what he is but that he cannot be anything else, how then can I form the concepts of genera and species, and rely on them? The qualities and attributes that I separated as fixed and static are nothing less than such; every being is indifferent to any other attribute, he receives and loses them without sufficient reason. So it is only by assuming the truth of beings, that is to say the immutability of their essence, and the permanence of their attributes, that we can organize them into these generic and specific categories, which are indispensable for forming the least bit of reasoning. The properties of numbers and figures would not be any more constant. Perhaps tomorrow two and two will be five, and a triangle will have four sides: if it were so, then all of science would lose its unique and unshakable foundation.
