Morality is more than simply considering consequences, it is a positing of specific ways to act. The consequences our actions have for others are usually considered, but that can be done 'morally' or 'immorally', for a given moral standpoint. The absolute validity of any moral standpoint, in the absence of any known absolutes, is a pretty fair topic, imho.
I have been reading a bit of Simone De Beauvoir's 'Existentialist Ethics' and find the positing of 'freedom of consciousness' as absolute, but not realised in action, pretty interesting. A summary of the position is below:
"Existentialism does have an ethical foundation, however; the difficulty lies in recognizing it. To recognize the foundations of existential ethics, one must recognize the “truths” behind the philosophy. The basis for most philosophical schools is a set of “universal truths” agreed upon by the proponents of the philosophy. The school can be simple, having just one rule: “There are no universal truths.” Of course, that rule is then a universal truth and a paradox. Existentialism’s basis is a simple set of truths relating to sentient life, as discussed in the opening paragraphs of this document:
* First, sentient beings exist, then they spend a lifetime defining an individual essence;
* All sentient life forms, namely humans, have free will;
* Every action, expression, or thought is the result of a decision;
* Decision making is a stressful, solitary act, even when part of a group; and
* Any decision can and usually does have negative aspects.
These “truths” form the foundation of existentialism. Existential values are those values recognizing the importance of free will, the anxiety experienced by others, and the potential consequences of decisions upon other beings, sentient and not. The foundations of any ethical system employed by existentialists can be reduced to the following statements:
1. Existentialism requires constant thought, expression, and action — the active development of one’s essence.
2. All decisions are individual, with each being responsible for his or her choices.
3. The most important decisions are those affecting the free will of other individuals, other matters are less important.
4. Some may be affected negatively, their choices reduced by a decision, so decisions must promote freedom among the greatest number of beings.
5. Limiting the number of options available to an individual in any situation reduces that being’s freedom to express a free will.
6. There is no such thing as a demand, since one can always accept death as a choice."
