Abstemius's Fables (Sir Roger L'Estrange)
287. (Abstemius 35) The Mice and the Oak.
The Mice found it so troublesom to be still climbing the Oak for every Bit they put in their Bellies, that they were once to set their Teeth to't, and bring the Acorns down to them; but some wiser than some, and a Grave Experienc'd Mouse, bad them have a care what they did; for it we destroy our Nurse at present, who shall feed us hereafter?
Resolution without Foresight is but a Temerarious Folly: And the Consequences of Things are the first Point to be taken into Consideration.
