“I don't like mixing up moralities with mathematics.”

“The game of life does not proceed like a mathematical calculation on the principle that two and two make four. Sometimes they make five, or minus four, and sometimes the blackboard topples over in the middle of the sum and the pedagogue is left with a black eye. ”

“I had a feeling once about Mathematics - that I saw it all. Depth beyond depth was revealed to me - the Byss and Abyss. I saw - as one might see the transit of Venus or even the Lord Mayor's Show - a quantity passing through infinity and changing its sign from plus to minus. I saw exactly why it happened and why the tergiversation was inevitable but it was after dinner and I let it go.”

“I contend that for a nation to try to tax itself into prosperity is like a man standing in a bucket and trying to lift himself up by the handle.”

“A man does what he must - in spite of personal consequences, in spite of obstacles and dangers and pressures - and that is the basis of all human morality.”

“We contend that for a nation to try to tax itself into prosperity is like a man standing in a bucket and trying to lift himself up by the handle.”

“This is the type of arrant pedantry up with which I will not put.”
