 According to Israeli, a human being can act in a number of ways when faced with a specific situation. The reason for this ability is the capacity of discernment, and more specifically of cogitation and consideration. Due to these capacities people are able to acquire theoretical and practical knowledge and to differentiate between good and evil. Because animals do not possess intellectual capacities, they are limited to acting in a definite way in particular situations. However, the ability of humans to act in different ways is a consequence of humans’ position between pure intellect and beast. People use their cogitation and consideration to attain a higher level of knowledge. However, as long as humans use those capacities their knowledge will remain imperfect and they will continue to hesitate and be uncertain. When they are united with intellect they no longer are uncertain and act in the best possible way in all situations without any tension in their soul. According to Israeli, the certainty of truth cancels all kinds of bad temptations.
