Ignorance is the mother of devotion

I've been saying it so long to you, you just wouldn't listen. Every time you said 'Farm Boy do this' you thought I was answering 'As you wish' but that's only because you were hearing wrong. 'I love you' was what it was, but you never heard.

Ignorance is the mother of presumption

I have loved but one flag and I can not share that devotion and give affection to the mongrel banner invented for the League of Nations

So long as the mother, Ignorance, lives, it is not safe for Science, the offspring, to divulge the hidden cause of things

If you would abolish avarice, you must abolish its mother, luxury
