Philosophically, one might fight that ACIM's core tenets are fundamentally mistaken due to their dependence on metaphysical assertions that can not be substantiated through reason or empirical evidence. ACIM posits that the planet we see with this feelings is an dream, a projection of our combined egos, and that true the truth is a non-dualistic state of great love and unity with God. That worldview echoes facets of Gnosticism and Western spiritual traditions like Advaita Vedanta, nonetheless it stands in marked distinction to materialist or empiricist views that take over a lot of contemporary idea and science. From the materialist point of view, the bodily world is not an impression but the only reality we are able to fairly study and understand. Any assertion that dismisses the tangible earth as pure dream without scientific assistance falls into the region of speculation rather than fact.

Theologically, ACIM deviates significantly from conventional Religious doctrines, which portrays uncertainty on its legitimacy as a spiritual text declaring to be authored by Jesus Christ. Conventional Christianity is made on the teachings of the Bible, which assert the truth of crime, the necessity of acim Christ's atoning compromise, and the importance of trust in Jesus for salvation. ACIM, however, denies the fact of failure, observing it instead as a misperception, and dismisses the necessity for atonement through Christ's compromise, advocating as an alternative for an individual awakening to the natural heavenly character within each individual. That radical departure from orthodox Christian values increases questions about the credibility of ACIM's supposed divine source. If the teachings of ACIM contradict the key tenets of Christianity, it becomes challenging to reconcile their states with the recognized spiritual custom it purports to align with.

Psychologically, the course's emphasis on the illusory character of suffering and the energy of your head to produce truth may be equally delivering and potentially dangerous. On a single hand, the idea that we can surpass suffering through a change in belief may allow people to seize control of these psychological and psychological states, fostering a sense of firm and inner peace. On the other hand, that perception may cause an application of spiritual skipping, wherever individuals dismiss or dismiss real-life problems and emotional pain under the guise of religious insight. By teaching that bad experiences are mere predictions of the ego, ACIM might unintentionally inspire individuals to avoid approaching underlying psychological dilemmas or engaging with the real-world factors behind their distress. This approach could be especially hazardous for people working with critical intellectual health conditions, as it can prevent them from seeking necessary medical or beneficial interventions.

Empirically, there's small to no clinical evidence encouraging the metaphysical statements made by ACIM. The idea that the physical earth is an illusion created by our collective vanity lacks empirical support and operates counter to the huge body of medical information accumulated through ages of statement and experimentation. While subjective experiences of transcendence and religious awareness are well-documented, they don't offer objective proof of the non-dualistic fact that ACIM describes. More over, the course's assertion that adjusting one's thoughts may alter truth in a literal sense is reminiscent of the New Thought action and the more new legislation of interest, equally of which have been criticized for missing clinical validity. The placebo influence and the power of positive considering are well-documented phenomena, but they don't help the grand metaphysical states created by ACIM.
