texts cannot be considered reliable source of Ājīvika history and philosophy, because "it seems doubtful whether a doctrine [of Ajivikas] which genuinely advocated the lack of efficacy of individual effort could have formed the basis of a renunciatory path to spiritual liberation", and that "the suspicion must be that the Jains and Buddhists deliberately distorted Ajivika doctrine for their own polemical purposes". In contrast, other scholars suggest that at least the common elements found about Ājīvikas in Jain and Buddhist literature may be considered, because Jainism and Buddhism were two different, competing and conflicting philosophies in ancient India. Philosophy Absolute determinism and no free will The problems of time and change was one of the main interests of the Ajivikas. Their views on this subject may have been influenced by Vedic sources, such as the hymn to Kala (Time) in Atharvaveda. Both Jaina and Buddhist texts state that Ājīvikas believed in absolute determinism, absence of free will, and called this niyati. Everything in human life and universe, according to Ajivikas, was pre-determined, operating out of cosmic principles, and true choice did not exist. The Buddhist and Jaina sources describe them as strict fatalists, who did not believe in karma. The Ajivikas philosophy held that all things are preordained, and therefore religious or ethical practice has no effect on one's future, and people do things because cosmic principles make them do so, and all that will happen or will exist in future is already predetermined to be that way. No human effort could change this niyati and the karma ethical theory was a fallacy. James Lochtefeld summarizes this aspect of Ajivika belief as, "life and the universe is like a ball of pre-wrapped up string, which unrolls until it was done and then goes no further". Riepe states that the Ajivikas belief in predeterminism does not mean that they were pessimistic. Rather, just like Calvinists belief in predeterminism in Europe, the Ajivikas were optimists. The Ajivikas simply did not believe in the moral force of action, or in merits or demerits, or in after-life to be affected because of what one does or does not do. Actions had immediate effects in one's current life but without any moral traces, and both the action and the effect was predetermined, according to the Ajivikas. Makkhali Gosala seems to have combined the ideas of older schools of thought into an eclectic doctrine. He appears
