Chapter 3 is about functional explanation in biology, rather than directly about mental content, but in this chapter the author defends a controversial premise of the methodological argument for teleosemantics (given in chapter 4). The premise is that physiologists and neurophysiologists ascribe normal-proper functions in explaining how bodies and brains operate for significant scientific reasons. How an organic system operates in the here and now depends on the actual causal contributions its components make in the here and now, and yet biologists also describe the normal-proper functions of components when explaining how (and not just why) complex organic systems operate or function the way they do. Central to the biologists’ task is describing systems that are functioning normally or properly (e.g., normal human visual systems, or normal human immune systems). The author explains how this role of a malfunction-permitting notion of function (sometimes called a “normative” notion) is consistent with the etiological theory of functions, but the aim here is not to establish the truth of the etiological theory of functions (which is defended in other works).

A chemical evolutionary model with a large number of species and a large chemical library is used to examine the principal chemical processes in interstellar clouds. Simple chemical equilibrium arguments show the potential for synthesis of very complex organic species by ion-molecule radiative association reactions.

Astrochemistry and astrobiology, the fascinating disciplines that strive to unravel the origin of life, have opened unprecedented and unpredicted vistas into exotic compounds as well as extreme or complex reaction conditions of potential relevance for a broad variety of applications. Representative, and so far little explored sources of inspiration include complex organic systems, such as polycyclic aromatic hydrocarbons (PAHs) and their derivatives; hydrogen cyanide (HCN) and formamide (HCONH2) oligomers and polymers, like aminomalononitrile (AMN)-derived species; and exotic processes, such as solid-state photoreactions on mineral surfaces, phosphorylation by minerals, cold ice irradiation and proton bombardment, and thermal transformations in fumaroles. In addition, meteorites and minerals like forsterite, which dominate dust chemistry in the interstellar medium, may open new avenues for the discovery of innovative catalytic processes and unconventional methodologies. The aim of this review was to offer concise and inspiring, rather than comprehensive, examples of astrochemistry-related materials and systems that may be of relevance in areas such as surface functionalization, nanostructures, and hybrid material design, and for innovative technological solutions. The potential of computational methods to predict new properties from spectroscopic data and to assess plausible reaction pathways on both kinetic and thermodynamic grounds has also been highlighted.
