I see what you're saying but I disagree on two counts.
Firstly, the author advocates not just personal experience but also following the examples of "great singular men of history". This is the classic traditionalist right-wing narrative whereby we need super-hero saviours past and present to show us plebs the way.
Secondly, the author doesn't just say to find your own values, but explicitly lauds a specific set of values:
> multiplication of biological kin, sovereign control of living space, eternal fame, rewards to friends and punishments to enemies, a universal benevolent impact, and harmony with the plans and laws of God and nature
These are traditionalist right-wing norms. Arguably they are pretty damaging in the modern world.
