When we feel that we can neither do a thing ourselves, nor even learn to do it by reason of its intricacy and difficulty, and that no one else ever can or will, and yet we see the thing none the less done daily and hourly all round us, then we are not content to say we do not understand how the thing is done, we go further and ascribe the action to God.

Context

“If we feel that we can identify ourselves with the steam and machinery of a steam engine, so as to travel in imagination with the steam through all the pipes and valves, if we can see the movement of each part of the piston, connecting rod, &c., so as to be mentally one with both the steam and the mechanism throughout their whole action and construction, then we say we understand the steam engine, and the idea of God never crosses our minds in connection with it. When we feel that we can neither do a thing ourselves, nor even learn to do it by reason of its intricacy and difficulty, and that no one else ever can or will, and yet we see the thing none the less done daily and hourly all round us, then we are not content to say we do not understand how the thing is done, we go further and ascribe the action to God. As soon as there is felt to be an unknown and apparently unknowable element, then, but not till then, does the idea God present itself to us. So at coroners’ inquests juries never say the deceased died by the visitation of God if they know any of the more proximate causes.” source
