Natural Law Ethics
‘The natural law moral theory banks on the claim that moral standards
are derived from the nature of the world and of human beings. Since
the eternal law of divine reason, according to St. Thomas Aquinas, is
unknowable to human beings, the law of nature is “nothing else than the
ganticipation of the eternal law in the rational creature.”

ultimate goal requires a consistent and proper use of intellectual and mera
virtues.
for Aquinas, humans naturally seek perfection to fully realize
their existence. They are naturally equipped with certain powers ox
“potentialities,” most especially, reason. An individual can reach his or
full potential as a human being only with the use of reason. ‘The proy
exercise of one’ natural capabilities to do good contributes to his or her
moral development. The morality of an action depends on whether itis
commensurate with or contrary to one’s nature as a rational being.
Conscience: Guide in Making Moral Decisions
For Thomas Aquinas, conscience is the natural faculty of hums:
reason to distinguish right from wrong. Such process of recognizing rig
from wrong is an innate intellectual activity that guides individuals
make moral decisions. Aquinas believes that the conscience has ™°
parts: synderesis and conscientia. The former is the innate ‘right re"
to know good and evil while the latter makes use of the synderesis 9 ™*
