Petrus Alphonsi,
Disciplina Clericalis — Prolog
(1919)
“ May God then who constrained me to write this little book and to translate it into Latin aid me in the undertaking. For when I wished to know by my own efforts the source of human life, I discovered that intellect was given to man by God for this purpose, that he might be zealous in the study of sacred philosophy as long as he lives; for by this he will gain more and better knowledge about his Creator and will strive to live temperately and know how to protect himself against threatening misfortunes ”
