Insufficient attention has been paid to the ways in which Newtonian conceptualizations of time encourage the view in contemporary psychology that only efficient causal explanations are viable, explanations that ultimately render meaningful, purposive, morally rich human actions and relationships illusory. In short, psychology’s pervasive adoption of Newtonian assumptions about time and causation renders the discipline incapable of understanding human behavior, its primary focus of study, in any but fundamentally inhuman ways. This paper aims (1) to provide a critique of the (...) Newtonian conception of time and its commitment to efficient causality, particularly as commonly present in contemporary psychological theory and practice, and (2) to examine the phenomenological account of time provided in the work of Emmanuel Levinas. Specifically, we will explore some of the ways in which Levinas’ account of time as fundamentally intersubjective provides an alternative conceptual grounding for understanding the therapeutic relationship as one of infinite ethical responsibility.
