Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 21 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“[A] state may classify with reference to the evil to be prevented, and ... if the class discriminated against is or reasonably might be considered to define those from -whom the evil mainly is to be feared, it properly may be picked out. A lack of abstract symmetry does not matter. The question is a practical one, dependent upon experience.... The state may direct its law against what it deems the evil as it actually exists without covering the whole field of possible abuses.”
