“A mathematician who is not also something of a poet will never be a complete mathematician.”

“The difference between the poet and the mathematician is that the poet tries to get his head into the heavens while the mathematician tries to get the heavens into his head.”

“As a poet and as a mathematician, he would reason well; as a mere mathematician, he could not have reasoned at all.”

“God's high freedom in Jesus Christ is His freedom for LOVE. The divine capacity which operates and exhibits itself in that superiority and subordination is manifestly also God's capacity to bend downwards, to attach Himself to another and this other to Himself, to be together with him. This takes place in that irreversible sequence, but in it is completely real. In that sequence there arises and continues in Jesus Christ the highest communion of God with man. God's deity is thus no prison in which He can exist only in and for Himself. It is rather His freedom to be in and for Himself but also with and for us, to assert but also to sacrifice Himself, to be wholly exalted but also completely humble, not only almighty but also almighty mercy, not only Lord but also servant, not only judge but also Himself the judged, not only man's eternal king but also his brother in time. And all that without in the slightest forfeiting His deity! All that, rather, in the highest proof and proclamation of His deity! He who DOES and manifestly CAN do all that, He and no other is the living God.”

“The union of the mathematician with the poet, fervor with measure, passion with correctness, this surely is the ideal.”

“To decide to become a philosopher seemed as foolish to me as to decide to become a poet.”

“Our aim as scientists is objective truth; more truth, more interesting truth, more intelligible truth. We cannot reasonably aim at certainty. Once we realize that human knowledge is fallible, we realize also that we can never be completely certain that we have not made a mistake.”
