 According to Alexander, we perceive the world directly: we do not perceive representations or ideas of tables, but the tables themselves (or aspects of the tables). We are conscious of our perceptual process, a consciousness he labels “enjoyment”. Any direct theory of perception must account for error. If we perceive the world directly, how do we make mistakes about it? Alexander’s answer is that we do not perceive the world incorrectly, but we can incorrectly apply partial perceptions to wholes. For example, we may correctly perceive a table as having a flat edge, but incorrectly apply that perception to the table as a whole.
