Let not the cobbler go beyond his last.
Let not the cobbler go beyond his last.
Meaning in plain English
Advice should recognise the boundaries of the adviser’s knowledge. The cobbler image cautions against extending authority beyond relevant expertise, while leaving room to learn, ask questions and contribute from experience.
Example
A skilled bookbinder comments on the condition of a volume but asks a language specialist to assess a disputed passage instead of presenting a guess as established fact.
Deeper explanation and when to use it
The cobbler’s last belongs to the work named in the proverb. Figuratively, familiarity with one task does not automatically establish authority over every neighbouring question. A useful response distinguishes what someone has directly observed from what they are assuming, then seeks the knowledge needed for the wider issue. This does not require silence from anyone outside a profession: a question, practical experience or an overlooked concern can still be valuable. Expertise itself may also need scrutiny. The saying is strongest as a reminder to state the scope and limits of a contribution, rather than as a rule that people must remain permanently within a fixed role.
When to use it
Use it when confidence from one field is being extended to a question requiring different knowledge.
Keep in mind
Respect relevant expertise without forbidding questions, learning or contributions from outside a formal role.
