The selection of topics for intensive research has often been a function of serendipitous opportunity. My forays into philosophy of education were largely in response to the prompting of friends and my dissatisfaction with much of what - at that time - passed for philosophy of education. I cannot honestly say that there has been either continuity or an overarching schema, though I suspect ,or at least hope, that someone who looked at my oeuvre might conclude that there was a philosophically integrated author.

In separating out, say, legal and moral requirements, I tend to work with paradigms rather than strict divisions - eg, paradigmatically, legal requirements are jurisdictionally bound whereas ethical requirements are aspirationally universal; ethical requirements focus especially on intentions whereas legal requirements focus primarily on conduct; ethical requirements take priority over legal requirements; and so on.

Structurally I don't see a fundamental difference between what we may reasonably expect of police and doctors - though obviously the fact that doctors are generally pursuing life-saving activities and police may be engaged in life-threatening activities may lead to differences in how we construe the moral limits to their roles.

I grew up in a home in which loyalty to family was central to my father's outlook. Adolescent changes to my outlook (which set me against parental values) made me very critical of loyalty, reinforced by certain religious writers I found influential at that time. Harry Blamires, The Christian Mind. But I remained conflicted about loyalty.

Whistleblowing constitutes a nice test case for the evaluation of loyalty. Loyalty also appears at the intersection of many major philosophical debates: general ones such as those between consequentialism and deontology, reason and feeling, virtue and principle, as well as more specific ones such as nationalism and patriotism, morality and obedience, particularism and universalism.

One of the real dangers of loyalty is that it may become associated with certain types of group-think, chauvinism, jingoism, and thus become socially destructive in ways that many other virtues are not likely to be when they are corrupted. Nationalism and patriotism are especially prone to misguided excess.
