Slavecraft: Being a grown up; Myth of training

I'm reading Slavecraft, written by "a grateful slave, with Guy Baldwin." This book came highly recommended by a submissive woman for whom I have great admiration and affection. The focus is deep 1L "erotic slavery", and the writer is a gay male slave. ("Erotic" is a nice adjective to add, to distinguish the glory of D/s slavery from the evils of nonconsensual slavery.) Of course, many of the ideas and arguments are useful in other kinds of relationships, in 1L and SL.

I'm not sure I agree with the slave on all things. But I find his perspective provocative. He describes the experience of being a slave in ways that help me better understand the challenges and joys. Here are some sections that stand out.

Sad to say, there are some who call themselves "Master" who are undeserving of the label. Some in need of an emotional hiding place will shield themselves behind the "Master" label. Lift the shield and one can often find those who shun real intimacy, self-disclosure, commitments of any sort, responsibility, honesty, their own vulnerability, self-knowledge, and yet, nevertheless, fear abandonment. (p. 15)

One in search of a Master (or a slave for that matter) is certain to encounter such people, and the challenge will be to discern the pretenders from the authentic. It is not enough for Masters to thrive on control; They must also crave responsibility and approach ownership with integrity, honor, honesty, common sense, and balance. There is no place in ownership for consuming rage, narcissism, viciousness, or other childish behavior. Ownership is for grown-ups. (p. 15)

The traditional slave-training myth asserts that: "Any self-proclaimed Master can teach a slave all he needs to know about surrender." (p. 39)

...one of the great ironies in all of this is that the training myth is often responsible for impeding both Masters and slaves in the refinement of their respective callings. Masters who feel insecure with Their abilities because of their ignorance about submission, or for other reasons, will often seek an inexperienced slave precisely because he won't know much. This allows the insecure Master to hide His ignorance from the slave and be superficially impressive. The irony is that such Masters could probably learn much more from experiences with already skilled slaves because then They could see how a well-developed slave functions, and thus learn the crafts of how to enjoy and develop a consensual slave.
