While atheism rejects the existence of God, it is not single system of philosophy.
Keeping this in mind, this post is a brief analysis of rationalism one of the important systems of philosophy in atheism.*

Rationalism, This system proposes reason as the basis of knowledge. It is a valid and proper system in its domain, which is limited, to be precise reason works best when it is accompanied with well defined data or concepts. This is generally not an issue when dealing with situations which are measurable ,because data is possible to obtain., however the cases which are merely observable , data is not always possible to be obtained. But there are more serious issues, reason is closely related to causality, and strictly speaking a method to investigate causes.
On itself (i.e. in absence of data and assumptions) it can neither handle the question of first cause, or define the value system.

Here the second point may be contentious, however viewing merely from reason neither the actions of lion or lamb have any value inherent, reason can operate only if man kind is either considered to be unique or some purpose assigned for the value.

In this way it fulfills neither the first nor the second criteria.

In this way, in my view rationalism is not a candidate for the the solution of dilemma.
