| The code is related to seriation, in that each letter corresponds to a number in a particular and precise order. |
| Between the ages of 7 and 12, the beginnings of logic appear in the form of classifications of ideas, an understanding of time and number, and a greater appreciation of seriation and other hierarchical relationships. |
| Conversely, the extrinsic properties of artifacts can provide chronological information that seriation cannot. |
| Stratigraphic and radiocarbon information can be used to give direction to the order produced through seriation and to begin to construct an absolute chronology. |
| Seriation is crucial to understanding the relations between numbers and hence to learning arithmetic. |
| There are noted, however, by Bonnier certain improvements made by Albertus on Aristotle's view of the seriation of living things. |
