"At the basis of identity lies a concept which throws light upon the teleological principle. This is the concept of the General. The basis of the principle of identity is a concept of species which embraces the general in contrast to the singular and particular; just as the judgment of Identity constitutes an advance to still greater Generality. The concept of the General which reaches expression in species coincides with the concept: Law of Nature. The Law is, for a particular circle of events, what the Species is for a particular circle of objects. As in the Species, the characteristics are expressed which an object must exhibit in order to belong to it, so in the Law the conditions are expressed which much exist in order that the instance included under it may take place. The relation of Identity to Causality is unmistakable. Species and Law include no mere plurality of objects and instances, for as often as the instance comes to pass the law is fulfilled, and the number belonging to a species is, in conception, limitless. Worlds like our earth may come into existence again and again; hence specimens of a certain species, eternally destroyed, may eternally renew themselves, and instances which fall under a certain law may eternally occur. Simply their conditions must exist in order that they may occur. Such cases form, therefore, a whole; and this is Totality in Little." The importance of every whole which sets itself over against the greater whole has already been noticed. The former whole constitutes the concept of Individuality which, as Undivided Unity, becomes independent. "The limitlessness which we claim for the whole is one of conception; we thus seek to make that which is incomprehensible conceivable." The concept does not need to be imagined; it may be thought. "Every one knows what he means when he opposes the whole to the part. The whole is not a larger part, but the opposite of the part, as 'all' constitutes the opposite of the many and the particular."
