### „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.“

— Proclo

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.
