<p>This review article explores the concept of the bacterial <i>other</i> by highlighting numerous ways bacteria recognize and interact with organismal and non-organismal entities in their environment. It expounds two patterns of bacterial otherness by drawing multiple examples from basal cognition and sociomicrobiology. These two patterns are the non-organismal other, i.e., the physical entities in the bacterial environment, and the organismal other, the living entities in the bacterial environment. By detailing numerous processes such as chemotaxis, learning, memory, kin recognition, altruism, predation, and cooperation, and analyzing these patterns of bacterial interactions, this review article also attempts to make a case for microbial bodily self.</p>
