Famous quotes containing the word conditions:
“The Supreme Court would have pleased me more if they had concerned themselves about enforcing the compulsory education provisions for Negroes in the South as is done for white children. The next ten years would be better spent in appointing truant officers and looking after conditions in the homes from which the children come. Use to the limit what we already have.”

“The worst of my actions or conditions seem not so ugly unto me as I find it both ugly and base not to dare to avouch for them.”
