Regarding his analysis of engraved stones in the Acheulean, John Feliks writes in his paper THE GRAPHICS OF BILZINGSLEBEN: SOPHISTICATION AND SUBTLETY IN THE MIND OF HOMO ERECTUS
"By employing extensions of engraved lines and points cognitive archaeology can access the geometric mind behind and beyond the artifacts themselves. This is possible because geometric extensions make accessible an invisible field of information outside of, but within the vicinity of, any given artifact. The extent of this field is more limited in some artifacts than in others, and the further out we go from various artifacts the more speculative the interpretations may be. However, depending on what specific information we are seeking, and despite what may be presumed, this is not necessarily the case, as suggested by Fig. 7.14, “Proof of association between an abstract point and infinity.” Depending on how the lines are organized, many interpretations of a surrounding field are perfectly safe.
Once the invisible geometric qualities are discovered and mapped out one can then genuinely access the thoughts of individuals who lived hundreds of thousands or even millions of years ago but who took the time to engrave a few lines. As difficult to believe as it may seem a vast amount of information that extends well beyond geometry and mathematical constructs is available that easily extends into the realms of philosophy by means of geometric equivalents or ‘cross-dimensional fractals.’ This is possible because all human cognition is based upon relationships between abstract points." (Feliks, page 82-83).
