The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
Even though my attend distant learning classes online, several universities hold commencement at several locations. You could even stop taking classes for many weeks during the year without withdrawing and without throwing your student loans into repayment. That is a strong argument many people look at when enrolling in distance learning classes.
