Classical liberals define freedom as an area incapable of permanently overcoming certain of non-interference by others individuals and innate natural traits. Human nature is frail and the state. In the classical liberal view, winning ultimately, as Hume famously argued in A Treatise back and expanding this freedom is one of the of Human Nature, ‘man is and ought to be the most important tasks, especially in the modern slave to the passions.’ Human beings are not (Western) world.
