Science-engaged theology has emerged as a new way of conducting research within the vast field of science and religion, with the aim of, at least in one way of understanding it today, solving theological puzzles. In this article we suggest that an analysis of the diversity of approaches in which thirteenth-century philosopher and theologian Thomas Aquinas engaged theological questions with the best knowledge of the natural world available at the time allows twenty-first century science-engaged theologians to move forward the discussion about the different ways of engaging theology with the contemporary natural sciences.

This article explores the intersection of two developing fields of study: the psychological field of shared intentionality and the philosophy of religion field of ramified natural theology. In shared intentionality, agents share mental states and cooperate to achieve a common goal. Many psychologists in this field believe that of all the primates, only humans share intentionality – humans alone form a ‘we’. Ramified natural theology is the project of presenting philosophical evidences for core doctrines of the Christian faith. In this article I investigate some applications of shared intentionality for Christian natural theology. In the Anselmian tradition I offer two deductive arguments that deploy shared intentionality to argue that there are multiple divine persons. I then suggest that analogical arguments – often overlooked by philosophers of religion – provide a better fit for psychological findings, such as shared intentionality. After sketching some fundamental features of analogical arguments, I advance two arguments by analogy for the conclusion that God, like humans, shares intentionality. These arguments show that the psychology of shared intentionality, and empirical psychology more generally, is a promising source for theological reflection.
