Bernard of Clairvaux (1090-1153) French religious, Doctor of the Church, saint
(Attributed)

Who loves me, loves my dog.

[Qui me amat, amat et canem meam.]

Festo Sancti Michaelis, Sermo 1, sec. 3 [tr. Trench (1853)]
Bernard says this is a common proverb.

Believe me, you will find more lessons in the woods than in books. Trees and stones will teach you what you cannot learn from masters.

[Experto crede: aliquid amplius invenies in silvis, quam in libris. Ligna et lapides docebunt te, quod a magistris audire non possis.]
