Abstract: A pathway is defined as an increasing sequence of subsets of $ ^\omega \omega $ which satisfy certain closure and boundedness properties. The existence of a pathway is shown to imply the existence of a P-point in $ \beta N\backslash N$. Pathways are shown to exist in any random extension of a model of $ {\text{ZFC}} + {\text{CH}}$.
