Early modern humans developed mental capabilities that were immeasurably greater than those of nonhuman primates. We see this in the rapid innovation in tool making, the development of complex language, and the creation of sophisticated art forms, none of which we find in our closest relatives. While we can readily observe the results of this high-order cognitive capacity, it is difficult to see how it could have developed. We take up the topic of cave art and archeoacoustics, particularly the discovery (...) that cave art is often closely connected to the acoustic properties of the cave chambers in which it is found. Apparently, early modern humans were able to detect the way sound reverberated in these chambers, and they painted artwork on surfaces that were acoustic “hot spots,” i.e., suitable for generating echoes. We argue that cave art is a form of cross-modality information transfer, in which acoustic signals are transformed into symbolic visual representations. This form of information transfer across modalities is an instance of how the symbolic mind of early modern humans was taking shape into concrete, externalized language. We also suggest that the earliest rock art found in Africa may constitute one of the first fossilized proxies for the expression of full-fledged human linguistic behavior. (shrink)

Using artificially synthesized stimuli, previous research has shown that cotton-top tamarin monkeys easily learn simple AB grammar sequences, but not the more complex AnBn sequences that require hierarchical structure. Humans have no trouble learning AnBn combinations. A more recent study, using similar artificially created stimuli, showed that there is a neuroanatomical difference in the brain between these two kinds of arrays. While the simpler AB sequences recruit the frontal operculum, the AnBn array recruits the phylogenetically newer Broca’s area. We propose (...) that on close inspection, reported vocal repertoires of Old World Monkeys show that these nonhuman primates are capable of calls that have two items in them, but never more than two. These are simple AB sequences, as predicted by previous research. In addition, we suggest the two-item call cannot be the result of a combinatorial operation that we see in human language, where the recursive operation of Merge allows for a potentially infinite array of structures. In our view, the two-item calls of nonhuman primates result from a dual-compartment frame into which each of the calls can fit without having to be combined by an operation such as Merge. (shrink)

Pockett has drawn an alternative conclusion from the data of Libet, Alberts, Wright, and Feinstein , and suggested that it takes 80 ms, rather than 500 ms, for the sensation evoked by a stimulus to enter awareness. Here, I suggest that our conscious sensation evolves over time, during the period from 80 to 500 ms after a stimulus, until the sensation is stably localized in space.

The phylogenetic position of the hagfish remains enigmatic. In contrast to molecular data that suggest monophyly of the cyclostomes, several morphological features imply a more ancestral state of this animal compared with the lampreys. To resolve this question requires an understanding of the embryology of the hagfish, especially of the neural crest. The early development of the hagfish has long remained a mystery. We collected a shallow‐water‐dwelling hagfish, Eptatretus burgeri, set up an aquarium tank designed to resemble its habitat, and (...) successfully obtained several embryos. By observing the histology and expression of genes known to play fundamental roles in the neural crest, we found that the hagfish crest develops as delaminating migratory cells, as in other vertebrates. We conclude that the delaminating neural crest is a vertebrate synapomorphy that seems to have appeared from the beginning of their evolutionary history, before the splitting away of the hagfish lineage.

Transcendental reflection does not simply withdraw from natural life and go somewhere else. On the contrary, it is a self-elucidation of natural life performed within this life itself. However, natural life has an inherent automatic system for concealing itself. Therefore, in order to make manifest the truly natural state of natural life, we need a deliberate method of outfoxing the natural attitude as it constantly tries to trick us. If so, the transcendental perspective is closely related to Husserl’s perplexing concept (...) of “primal I”. It expresses a primitive perspective of our experience that cannot be identified with the first-person perspective. Phenomenology is not merely an investigation of experience from the first-person point of view, but a philosophical thinking from a “zero person” perspective that makes it possible for us to understand the relativity of our own first-person experience, and how it is related to other first-person experiences and the third-person perspective.

This article considers Socrates's conception of courage in Plato's Socratic dialogues. Although the Laches, which is the only dialogue devoted in toto to a pursuit of the definition of courage, does not explicitly provide Socrates's definition of courage, I shall point out clues therein which contribute to an understanding of Socrates's conception of courage. The Protagoras is a peculiar dialogue in which Socrates himself offers a definition of courage. Attending to the dramatic structure and personalities of the dialogue, I will (...) point out that Socrates does not commit to the definition and that the hedonism and the definition of courage are used to disclose Protagoras's confusion regarding virtue. Following one of the clues within the Laches I will turn to the Apology and indicate Socrates's conception of courage which is based on his awareness of lack of knowledge of death and his religious conviction that nothing will happen for the good in life or in death. Finally I will show that such conception of Socratic courage satisfies the criteria in the Laches. (shrink)
