Why learn about philosophy? Because it is the master subject, more fundamental than all of the others.
Philosophical discourse critically examines fundamental assumptions and presuppositions without which one cannot be truly intellectually autonomous.
Why learn about libertarianism? Because politics causes or exacerbates the very problems that it purports to solve, misperceiving voluntary behaviour and free markets as problems.
Liberty is always preferable. Its maximal practical observance entailing self-ownership, private property and consensual interactions. And libertarianism will be the ideological framework of the future of humankind.
These bold claims are expounded and defended in J P Lester's Two Dialogues: Introduction to Philosophy and Libertarianism. Amusing and stimulating, these brief introductions to philosophy and libertarianism offer a unique insight and can be read without prior knowledge of the subjects.
Lester's often highly unorthodox critical commentary makes this a sharp and necessary read.
