Quote by Margery Allingham
He did not arrive at this conclusion by the decent process of quiet, logical deduction, nor yet by the blinding flash of glorious intuition, but by the shoddy, untidy process halfway between the two by which one usually gets to know things.
Summary
This quote is suggesting that the person in question did not come to their conclusion using a straightforward, logical approach or through a sudden revelation of insight. Instead, their understanding was formed through a messy and imperfect combination of both methods. It highlights that this is typically how people acquire knowledge – not entirely methodical or entirely spontaneous, but rather a blend of both processes.
