About に照らして・に照らすと

()らして is an expression based on the standard meaning of the う-Verb ()らす 'to illuminate', and is primarily used comparatively in a similar way to 'in light of' in English. This comparative meaning aims to illustrate (B) from the perspective of (A), and usually refers to situations, level of experience, or something similar.
To use this structure, attach the case-marking particle に to the end of a noun, then follow it with ()らして. If a second noun will be modified directly, then ()らした will be used instead.

  • 犯罪者(はんざいしゃ)刑法(けいほう)()らして(ばっ)せられる。
    Criminals are punished in accordance with the law.
Keep in mind that the に in this structure is marking (A) as the 'doer' of ()らす 'to illuminate', as it is a transitive verb. This means that the structure has a more literal translation of '(B) as reflected by (A)'. This can also be thought of as 'as made clear by (A), (B)', 'as made evident by (A), (B)'. (B) will almost always be a judgment that is logically based on (A).
