 Empirical things or existents are… groupings within Space-Time, that is, they are complexes of pure events or motions in various degrees of complexity. Such finites have all the categorial characters, that is, all the fundamental features which flow from the nature of any space-time… [A]s in the course of Time new complexity of motions comes into existence, a new quality emerges… The case which we are using as a clue is the emergence of the quality of consciousness from a lower level of complexity which is vital [i.e., life]. (Alexander 1920ii: 45)
