In contrast to his longtime friend and colleague Salah al-Din al-Bitar, who was more practical when it came to politics, Aflaq was a "visionary, the dreamer rather unfitted for political life". Aflaq was described by his associates as an "ascetic, shy and intense figure living a simple and unpretentious life." He has been accused of seeking help from other people instead of fulfilling his goal by himself or with others he led; Aflaq collaborated with Gamal Abdel Nasser, Abd al-Karim Qasim and Abdul Rahman Arif in 1958, to Ahmed Hassan al-Bakr and Ali Salih al-Sadi in 1963 and finally in the 1970s to Saddam Hussein. There are several Ba'athists, mostly from the Syrian-led Ba'ath Party, who believe Aflaq stole Ba'athist ideology from its original founder, Zaki al-Arsuzi. These individuals have denounced, and labelled, Aflaq as a "thief".
