'...human nature is not a master, distinct from us, reducing us to bondage. It is the deep structure of what we really are. The fact that we are not free to be other than human doesn't mean that we aren't free; how could it truly be freedom to be false to ourselves? Blue may as well demand the liberty to be red, odd the liberty to be even, vegetable the liberty to be mineral. That kind of liberty is just the liberty of self-annihilation. But if true freedom doesn't lie in being false to ourselves, then as the old adage claims, it must lie in being true to ourselves.'
J Budziszewski, On the Meaning of Sex, p.7.
