Context: The fact that all Mathematics is Symbolic Logic is one of the greatest discoveries of our age; and when this fact has been established, the remainder of the principles of mathematics consists in the analysis of Symbolic Logic itself.

“The presentation of facts in logical form contributes to a confusion between discovery and proof.”
Sarvepalli Radhakrishnan (1888–1975) Indian philosopher and statesman who was the first Vice President and the second President of India
Internet Encyclopedia of Philosophy
Context: The presentation of facts in logical form contributes to a confusion between discovery and proof. If the process of discovery were mere synthesis, any mechanical manipulator of prior partial concepts would have reached the insight and it would not have taken a genius to arrive at it.

“There is a logic of language and a logic of mathematics.”
Thomas Merton (1915–1968) Priest and author
The Secular Journal of Thomas Merton (1959)
Context: There is a logic of language and a logic of mathematics. The former is supple and lifelike, it follows our experience. The latter is abstract and rigid, more ideal. The latter is perfectly necessary, perfectly reliable: the former is only sometimes reliable and hardly ever systematic. But the logic of mathematics achieves necessity at the expense of living truth, it is less real than the other, although more certain. It achieves certainty by a flight from the concrete into abstraction. Doubtless, to an idealist, this would seem to be a more perfect reality. I am not an idealist. The logic of the poet — that is, the logic of language or the experience itself — develops the way a living organism grows: it spreads out towards what it loves, and is heliotropic, like a plant.
