At any time; there is only oneself. All sensory perceptions are self engineered so self could perceive itself as differentiated so not to feel by itself. It is not good to be alone. Truth is simple. Otherness does not imply separateness. There are no others really. Otherness is self-perceived for togetherness with togetherness being a synonym for companionship, friendship, love. In nuce. Self is an absolute monist with a heart of gold.
