Sieyès was always considered intellectual and intelligent by his peers and mentors alike. Through the virtue of his own thoughts, he progressed in his ideologies from personal experiences. Starting at a young age, he began to feel repulsion towards the privileges of the nobility. He deemed this advantage gained by noble right as unfair to those of the lower class. This distaste he felt for the privileged class became evident during his time at the Estates of Brittany where he was able to observe, with dissatisfaction, domination by the nobility.
