key aspects
telos
four tiers of law
synderesis
3 primary precepts
split into 5
1. worship god
2. ordered society
3. reproduction
4. learning and education
5. death (prevent it)
BUT aquinas wasnt giving a definitive list, this listing was done by later catholic manualists.
and Aquinas also said ‘and so forth’ to assert that his understanding wasn’t set in stone.
secondary precepts
real and apparent goods
double effect
provide a moral framework for evaluating actions that have both a good and a bad effect, ensuring the action is permissible if it meets conditions
1) the action itself is morally good or neutral
2) the agent intends only the good effect, not the bad
3) the good effect is not produced by means of the bad effect
4) the good effect disproportionately outweighs in importance the bad effect
problems with double effect 4
s, c, jj, mc
casuistry and manualist
applying laws with reason= criticism of those who are too concerned with rules and not enough with justice.
the catholic church has given great emphasis to rules and less orthopraxy = MANUALIST
matthew 6:2 - intentions
So when you give to the needy, do not sound a trumpet before you
aristotle quote
“nature makes nothing without a purpose”
Louis Pojman
developed principle of double effect
notes that Aquinas’ position is absolutist. “humanity has an essentially rational nature, and reason can discover the right action in every situation”
cases
strengths of natural law x4
+ absolutist, provide clarity and firm moral principles
+ the secondary precepts are intended to be reasoned within the context of a society = flexibility
+ primary precepts are general consensus on desirable goods in human life.
+ values life and rights. Grotius says that human rights are evident when looking at nature.
weaknesses of natural law x3 gen
na, lae, outd
weakness of telos x2
more arguments to give and counter x3
bbw, r,nr
+ offers best of both worlds where firm primary precepts but flexible when applying secondary precepts.
BUT - there is tension between the idea that natural law is “universal in its precepts” and “application of the natural law varies greatly” (CATECHISM 1956-7)
+Reliance on reason makes it fairly rational.
BUT - some think eg calvin that it reduces the role of scripture. also augustine thinks we have lost rational facilities in the fall
+ natural law defends natural rights
BUT Bentham says natural rights are “nonsense on stilts”
books aquinas, aristotle, catholics
aquinas - summa theologica
aristotle - Physics II 3
catechism of the catholic church 1956-7
Rachels criticism
just because sex means reproduction, doesn’t mean this is its only purpose
John Finnis x2
it upholds natural rights
also proves it is adaptable as although he rejects god, he puts forth a version without god
Polkinghorne
science can answer the what but not the why = cannot rule anything out
jeremiah 29:13
“the plans and the purposes that god has for human beings” = TELOS
francis bacon
only the material and the efficient causes are scientific, formal and final are not
