Commentary on Meditations: B5:14

Reason and the art of reasoning are faculties self-determined by their own nature and their own products. They start from the relevant premise and follow the path to the proposed end. That is why acts of reason are called 'right' acts, signifying the Tightness of the path thus followed.

Like rays of light from the sun, 'right acts' of virtue just are.  From inception of thought (reason in man) to the carrying out of the act ('the proposed end), they are one and the same.  No context is needed.  They stand alone and attain their own end.
