In society today, we define Nature as something that is not made by humankind but rather is instinctual. St Thomas Aquinas (1225-74) believed our telos can be discovered by using our human reason to reflect on our human nature and work out what we need to do in order to achieve our particular telos.

This idea can be divided into two kinds of ‘good’; Apparent good and Real good.

In light of this quote it shows that reason is an intrinsic aspect of humans in order to work out our true self. When we act in our
