what is aquinass natrual law
Natural law is the theory that God has designed a moral law into human nature such that we are naturally inclined to certain moral behaviours. Ethics is therefore about using reason to discover the natural law within our nature so that we can conform our actions to it in order to fulfil our purpose (telos) of glorifying God, by following his law.
natrual law quote
the light of reason is placed by nature in every man, to guide him in his acts towards his end”.
What are the four tiers of law
The four tiers of Law. The ultimate source of moral goodness and thus law is God’s nature, which is the eternal law. However, that is beyond our understanding, so we have access to lesser laws that derive from the eternal law.
Eternal Law – God’s omnibenevolent nature.
Divine law – God’s revelation to humans in the Bible.
Natural law – The moral law God created in human nature, discoverable by human reason.
Human law – The laws humans make which should be based on the natural and divine law.
The purpose of the four tiers is to show how Aquinas thinks that human law can gain its authority by deriving from the natural and divine law which themselves ultimately derive authority from God’s nature.
what was aristotles influence on aquinas
Aquinas was influenced by Aristotle’s views that there is a natural end to things – everything has a purpose (telos) built into it by its nature – the final cause. Whereas Aristotle thought the final cause of all things was the prime mover, Aquinas Christianised the concept and claimed that it was God. The telos/end/goal of rational beings is the good, which is God’s eternal law. God created us and our nature to have the telos of glorifying God. We can use our God given reason to figure out the inclinations of our God-designed nature
modern science rejection of telos / final causation francis
ncis Bacon, called the father of empiricism, argued that formal and final causation (telos) have no place in empirical science but are instead matters for metaphysics. He thought purpose was a divine matter. Regarding form, he gave the illustration of the ‘whiteness’ of snow and explained how science could investigate how snow results from air and water, but this only tells us about its efficient cause, not the form of ‘whiteness’, which is thus not a scientific matter.
modern physics rejection of telos
Modern physics goes even further than Bacon in its rejection of final causation. A deterministic universe operating by the laws of physics seems to be completely without purpose. All supposed telos of an object can be reduced to non-teleological concepts regarding the material structure of an object. This suggests there is no basis for grounding telos in God like Aquinas did, or in grounding it as a required explanation of change in objects like Aristotle did. Modern science can explain the change and apparent purpose in the world without telos.
science reposponse to modern physics
Science cannot rule out something like a prime mover or God which could provide telos, however.
Nonetheless, at the very least the current scientific understanding of the universe works without the need for any kind of telos. A century after Bacon, Laplace wrote a book on the workings of the universe, claiming to have ‘no need’ of the hypothesis that there is a God. More recently, Stephen Hawking made the same claim.
how does synderisis relate to reason
Aquinas claims that reason is a power of the human soul and synderesis is the habit or ability of reason to discover foundational ‘first principles’ of God’s natural moral law which gives us insight into God’s intentions for human life and thus our telos.
quote about synderisis
he first practical principles … [belong to] a special natural habit … which we call “synderesis” …
what does the first principle synderisis say
The first principle synderesis tells us is called the synderesis rule: that the good is what all things seek as their end/goal (telos). This means that human nature has an innate orientation to the good.
“This therefore is the principle of law: that good must be done and evil avoided.
link synderisis to primary precepts
In addition to this, synderesis tells us the primary precepts: worship God, live in an orderly society, reproduce, educate, protect and preserve human life and defend the innocent. These primary precepts are the articulation of the orientations in our nature toward the good; the natural inclinations of our God-designed human nature, put into the form of ethical principles by human reason.
weakness of the first principle synderisis rule
Arguably Aquinas is too optimistic about human nature. If you consider the terrible things that humans have done and that entire cultures have embraced, e.g. slavery and Nazism, it starts to look like human nature is not as positive as Aquinas thought. If we really had an orientation towards the good and the primary precepts accurately described our nature’s orientation, then we should not expect to find the extent of human evil we do.
reponse from aquinas towards the critic on first synderisis principle
However, Aquinas’ claim is merely that human nature contains an orientation towards the good, it doesn’t involve a commitment to humans actually doing more good than evil, nor to incredibly evil acts or cultures occurring infrequently. Aquinas acknowledges that there are many reasons we might fail to do good despite having an orientation towards it. These include original sin, mistakes in conscientia, lacking virtue and a corrupt culture.
what are secondary precepts quote
“there belongs to the natural law, first, certain most general precepts, that are known to all; and secondly, certain secondary and more detailed precepts, which are, as it were, conclusions following closely from first principles
what are secondary precepts
The primary precepts are applied to situations or types of actions – a process called conscientia. The judgement we then acquire is a secondary precept. E.g euthanasia: the primary precepts don’t say anything about euthanasia exactly, but we can use our reason to apply the primary precepts to euthanasia, and realise that it goes against the primary precept of protecting and preserving human life. Arguably it even disrupts the functioning of society too. Therefore, we can conclude the secondary precept that euthanasia is wrong.
