“O matemático especula as causas de um certo efeito sensível, sem considerar sua existência real; pois a contemplação de universais exclui o conhecimento de particulares; e aquele cujo olhar intelectual está fixo naquilo que é geral e abrangente, pouco pensará naquilo que é sensível e singular.”

The mathematician speculates the causes of a certain sensible effect, without considering its actual existence; for the contemplation of universals excludes the knowledge of particulars; and he whose intellectual eye is fixed on that which is general and comprehensive, will think but little of that which is sensible and singular. <br class="br">The philosophical and mathematical commentaries of Proclus on the first book of Euclid&#x27;s Elements: To which are added a History of the restoration of Platonic theology by the latter Platonists, and a translation from the Greek of Proclus&#x27;s Theological elements, Volume 1, página LXVII https://books.google.com.br/books?id=AD1WAAAAYAAJ&amp;pg=PR67, Proclus, ‎Marinus - 1792
