argument from degree

First proposed by St Thomas Aquinas, the Argument from Degree states: Objects have properties to greater or lesser extents. If an object has a property to a lesser extent, then there exists some other object that has the property to the maximum possible degree. Hence, there is an entity that has all properties to the maximum possible degree, and this entity is God.

refutation :

Just because we can conceive of an object with some property in a greater degree does not mean that such an object exists. This reminds me of the Ontological Argument. We could also apply The Perfect Island to this argument. Islands have properties, therefore, a perfect island with all properties to the maximum degree must exist... but it doesn't. This again is a false conclusion based on flawed logic
