Understanding Consequentialism and Utilitarianism: A Mini-Lecture, Study notes of Computer Science

An overview of consequentialism, a moral theory that emphasizes the importance of consequences, with a particular focus on utilitarianism. Different varieties of consequentialism, critiques of utilitarianism, and key figures such as bentham and mill. It also touches upon related topics like cost-benefit analysis and ethical decision-making.

Consequentialism mini-lecture
Remember, class answered questions in survey about ethics being about what
happens, or judging a person by actions, not speech.
Implies an emphasis on consequences is a public morality. And it's in
policymaking, not personal professional ethics that we see it most at work.
Different varieties. Most influential is utilitarianism.
Egotism
Anybody read any Ayn Rand? What do you think? The intelligent, creative leader
trying to create a better world despite being dragged down by dull bureaucrats....
But mostly egotism is a straw-man ethics that ethics needs good response to.
Why should I care about anybody else? It's a dog-eat-dog world, etc... Won't go
into that in this course.
But egotism DOES apply and is taken seriously at the public level. Company
interest and national interest are not obviously illegitimate. Much of business law,
ideology, economics and international politics assumes underlying competition &
exercise of power. Think about this.... What (if any) limits are there to pursuing
one’s company interest as a professional?
Reflection on cost-benefit analysis exercise
1. Did anybody get a result that they "didn't want"? Does this invalidate the whole
process? Is it really a decision procedure, or is it really a way to surface weights
and ascribed values?
2. How sensitive is the outcome to the assignment of numbers to outcomes? Is it
reasonable to reduce everything to commensurable numbers? Why 1,3,9 and not
1,2,3 or 1,5,25? Wouldn't these accidental choices of procedure make a big
difference? Are the numbers sensitive to probabilities of outcomes as well as
their values? (cf. decision analysis)
3. Who says that some stakeholders deserve more weight than others? (But it
forces you to be explicit.)
4. What about rules or principles that trump all of these issues? E.g.
constitutional protections of free speech in the case of PICS.
Basic notions of utilitarianism
Consequentialism without problems of self-interest/egotism. Liberalism (i.e.

  4. What about rules or principles that trump all of these issues? E.g. constitutional protections of free speech in the case of PICS. Basic notions of utilitarianism Consequentialism without problems of self-interest/egotism. Liberalism (i.e.

emphasis on the freedom of the individual to choose action and justify behavior) without selfishness. Priestley: "Greatest good to the greatest number." (Influenced Franklin as well as Bentham). Contrast with the cost-benefit exercise, where we identified specific shareholders and decided which ones counted more than others. Bentham: Historical context: No need to know this, but the people had colorful lives. Progressive thought to oppose tradition, establishment of religious morality. One of the founders of the University of London, which did not require allegiance to CoE, unlike Oxford and Cambridge. (He also designed architecture of UCL). Also designed an unbuilt model prison: the Panopticon. (This isn't strictly relevant to utilitarianism but to Privacy.) Replacement of cruelty and physical punishment by prisoners' self-regulation -- but chief mechanism is potential for surveillance. cf. 1984? Mention Foucault whose view was that modern technological society was a panoptic prison. E.g. piecework payment for production line labor. Discuss telephone monitoring of service calls? Workplace surveillance? Very dry and boring texts and uneventful, sheltered (childlike) life. Gave his walking stick and teapot names. Nietzsche: "Soul of washrag, face of poker, / Overwhelmingly mediocre." But despite himself left a bizarre panoptic legacy -- maybe he had a witty streak after all. Embalmed and brought out for U. London Senate meetings. [Read Tyranny of Numbers: pp. 16-17.] "Maximization" was word invented by Bentham -- also "international" and "codify". But then he also wanted to call astronomy "uranoscopic physiurgics." You can't win them all. Basic idea is an economic metaphor of balancing interests, defining the good as that which maximizes benefits overall. Democratization as opposed to special interests or power. Spent life articulating greatest good principle, but issue here, who is "everyone"? Peter Singer thinks we should include animals too. And what about the tyranny of the majority? "Pushpin" vs. "poetry" If the majority favors simple pleasures, it's elitist to insist on anything else. (cf. the CBA exercise where we couldn't ask the stakeholders their preferences, but decided for them.)

need for a lot of relevant "is" knowledge as a background for making "ought" judgments.) Later utilitarianists argue that bounded rationality implies that we should use rules of thumb (i.e. ethical principles) as ways to satisfice consequences in situations like the one the decision maker faces. But then the same questions arise: how do you know which rules lead to what outcomes? Impossibility of measurement: Whether the outcome is measured in terms of happiness or pleasure or preference satisfaction, what are the units of measurement and how are they measured? (We used a three-point logarithmic scale -- but why??) Modern CBA for public programs usually reduces everything to money. (Often with complex accounting rules to account for future value.) This might work for an intellectual property policy (or not) but how do you quantify outcomes about access to information by minors in monetary terms? Should you? In summary Utilitarianism doesn't work in practice the way Bentham proposed. But it's a good idealization of what we should do if we are concerned with stakeholders and have influence over policymaking. The problem is matching ideals to practical procedure -- e.g. by obtaining estimated outcomes and combining them fairly. There are more fundamental objections -- especially for use in personal ethics -- that outcomes are irrelevant when courses of action could violate obligations -- either prior commitments or universal laws and principles such as rights.
