I don't see why we can apply these words and ideas to humans but not to bacteria. Our feelings (wants) and actions are a result of evolution just the same as bacterial action. We may choose not to ascribe feelings to bacteria, but the origin of the motivation is precisely the same as it is in humans - the motivation to survive and reproduce is universal to organisms.
