“Seeing much, suffering much, and studying much, are the three pillars of learning.”
A Welsh triad cited in A Vindication of the Genuineness of the Ancient British Poems of Aneurin, Taliesin, Llywarch Hen, and Merdin (1803), by Sharon Turner, reads, "The three pillars of learning; seeing much, suffering much, and studying much". This was quoted from Turner by Isaac D'Israeli in his The Amenities of Literature (1841) and, through the confusion of father with son, has come to be falsely attributed to Benjamin Disraeli.
