This article presents silence as a cognitive tool to comprehend the environment. Two dimensions of silence are addressed: a natural mechanism and human beings' social and cultural construction. There is a link between these two dimensions because, on the one hand, agents' cognitive strategies based on silence influence how meanings and uses of silence have been constructed. The meanings of silence we use are contextual shapers of silence-based cognitive strategies. Silence is analyzed as a resource for coping with ambiguity: situations perceived as uncertain provoke doubt and confusion because they can be understood differently or suggest different interpretations. These situations can occur in the face of epistemic disruption. The consequence is a transfer of the ambiguity property of these situations to the usual ways of relating to the world and people. The cognitive approach is based here on a semiotic-hermeneutic interpretation of silence from a phenomenological perspective. This accounts for a paradox: even if silence does not exist (the world is acoustic), it is real. The silence experience is a non-inferential cognitive capacity located at the base of perception: a stimulus that suggests a particular gesture as an action different from the usual one to deal with the environment.

In addition to natural curiosity, science is characterized by a number of psychological processes and perceptions. Among the psychological features, scientific enquiry relates to uncovering—or discovering—aspects of a world perceived as hidden from humans. A speculative theoretical model is presented, suggesting the evolution of science reflects psychological repercussions of wearing clothes. Specifically, the natural world is perceived as hidden due to the presence of clothing. Three components of scientific enquiry may arise from clothing: detachment from sensual experience, a perception that the world is veiled in mystery, and an intellectual desire to uncover the hidden structure of nature. Rather than beginning with the emergence of Homo sapiens, the proposed connection with clothing implies that psychological foundations for science began to develop during the last ice age, with the invention of complex clothes that fully covered the human body. After the end of the last ice age, elements of scientific thinking began to emerge in societies where clothing was worn routinely for psychosocial reasons, including modesty. Notably, a scientific attitude was essentially absent in hunter-gatherer communities where nakedness remained the norm. This novel perspective aims to advance the history and philosophy of science, revealing the emergence of science as a situated phenomenon contingent on humans being covered.

The study of complex systems, although an interdisciplinary endeavor, is considered as an integrating part of physical sciences. Contrary to the historical fact that the field is already mature, it still lacks a clear and unambiguous definition of its main object of study. Here, I propose a definition of complex systems based on the conceptual clarifications made by Edgar Morin about the bidirectional non-separability of parts and whole produced by the nature of interactions. Then, a complex system is defined as the system where there is a bidirectional non-separability between the identities of the parts and the identity of the whole. Thus, not only the identity of the whole is determined by the constituent parts, but also the identity of the parts are determined by the whole due to the nature of their interactions. This concept allows, as shown in the paper, to derive some of the main properties that such systems must have as well as to propose its mathematical formalization.
