We can in fact only define a weed, mutatis mutandis, in terms of the well-known definition of dirt – as matter out of place. What we call a weed is in fact merely a plant growing where we do not want it. – E.J. Salisbury, The Living Garden, 1935
Sane judgment abhors nothing so much as a picture perpetrated with no technical knowledge, although with plenty of care and diligence. – Albrecht Durer
