 Dennett’s point is that avoidance itself is a high-level concept. As such, it is compatible with a deterministic bottom level (because the concepts at the emergent level are, by design, independent from the micro-laws). The physical description and the design description of Life are different interpretations of the same basic ontology, namely, the sparse ontology of CA. While in theory we could avoid the introduction of emergent concepts, in practice it is only by speaking of gliders, movements and avoidance that we can make sense of the evolution of the system (Dennett 2003: 43–44). Even without knowing Life’s physics, we could do a good job if we predicted the future by mentioning only high level patterns. Life is just a toy universe but, Dennett claims, these new intuitions are sufficient to see that, in some deterministic worlds, something is avoidable. For instance, it is true at the design level that gliders actually avoid eaters. Thus, the inference from determinism to inevitability can be blocked.
