Spiritual practice goes nowhere if it follows this path. Everything gets lost in interpretation, conceptual thinking, unacknowledged prejudice and bias, etc.
In spiritual practice, we have to dispense completely with appeals to justice and fairness, precisely because they are open to interpretation and dependent on position. And if we claim access to a higher truth, we are, in effect, claiming the power and the right to decide for others.
Aside: I dislike and avoid the notion that spiritual truth is a higher truth, in terms of society and the world, etc. Spiritual practice is based on a principles that run counter to many principles of society. To claim that spiritual practice is a "higher truth" is another form of prejudice. Instead, I have to acknowledge that the principles on which I base my decisions are different from the principles that a person in a social context may base his or her decisions.
I now rarely try to persuade people to adopt a specific perspective, Buddhist or otherwise. Rather, I seek to help them find what is true for them in the world they experience. As we explore this together, appeals to justice or fairness are almost always stories that hide or protect unacknowledged hurts or pains. As they open to those pains, people frequently find clarity on their own and know what to do, not because it is "fair" or "just" or "right" (these are, in the end, somewhat childish motivations), but because, when everything, inside and out, is included in awareness, often only one course of action is indicated — the direction of the present, to use Uchiyama's phrase.
