Hume argues that we should consider what impression gives us our concept of self. He contended that humans tend to think of themselves as selves like stable entities that exist over time. Nevertheless, he is convinced that no matter how closely we examine our own experiences, we never observe anything beyond a series of transient feelings, sensations, and impressions. We cannot observe ourselves, or what we are, in a unified way.
There is no impression of the “self” that ties our particular impressions together. In other words, we can never be directly aware of ourselves, only of what we are experiencing at any given moment. He contended that the self is just a bundle of perceptions, like links in a chain.
