Craig Biddle speaks on the difficulties of defending and justifying liberty for others. According to him, there are many reasons why there is often a tendency to reject ideas of liberty. Genuine liberty results in important discrepancies in wealth. Over-simplified arguments and the failure to hold certain axioms true, are often challenges to its understanding.

For Biddle, using purely economic arguments is not enough. The solution lies in employing a philosophical and properly essentialist case for liberty. He uses a trinity to define the main important principles of liberty as independence, individualism, and individual rights. Independence is the idea that an individual’s life belongs to him/her, that the individual is sovereign and an end to him or herself. The individual is a fundamental unit who acts on individual rights, or moral principles that identify his/her proper freedom of action in a social context.

This trinity of liberty, Biddle says, should be unified as a manifestation of a broader value: the morality of egoism.. This morality of self interest and self responsibility states that each individual should hold the fruits and consequences to their actions. That each individual is responsible for its own life and needs, and also holds the benefits to their thoughts and effort. In order to defend liberty, advocates of liberty must broaden the realm of their concern, and have rational, objective arguments that are understood by others.
