Background

The phrase is commonly attributed to
Søren Kierkegaard

, though he never used the term "leap of faith", but instead referred to a "qualitative leap".
The implication of taking a leap of faith can, depending on the context, carry positive or negative connotations, as some feel it is a virtue to be able to believe in something without evidence while others feel it is foolishness, as is presented in
Fear and Trembling
''Fear and Trembling'' () is a philosophical work by Søren Kierkegaard, published in 1843 under the pseudonym ''Johannes de silentio'' (Latin for ''John of the Silence''). The title is a reference to a line from Philippians 2:12, which says ...
on Abraham's figure when God demands the sacrifice of his son Ismail (Ishmael):
If Abraham had doubted as he stood there on Mount Moriah, if irresolute he had looked around, if he had happened to spot the ram before drawing the knife, if God had allowed him to sacrifice it instead of Ismail—then he would have gone home, everything would have been the same, he would have had Sarah, he would have kept Ismail, and yet how changed!
Development of concept by Kierkegaard

A leap of faith, according to Kierkegaard, involves
circularity as the leap is made ''by'' faith. In his book ''

can emerge. But this thinking about itself never accomplishes anything." Kierkegaard says thinking should serve by thinking something. Kierkegaard wants to stop "thinking's self-reflection" and that is the movement that constitutes a leap.

in conflict with the
liberal theological establishment of his day. His works included the orthodox Lutheran conception of a God that unconditionally accepts man, faith itself being a gift from God, and that the highest moral position is reached when a person realizes this and, no longer depending upon her or himself, takes the leap of faith into the arms of a loving God.
Kierkegaard describes "the leap" using the story of
Adam and Eve
Adam and Eve, according to the creation myth of the Abrahamic religions, were the first man and woman. They are central to the belief that humanity is in essence a single family, with everyone descended from a single pair of original ancestors. ...
, particularly Adam's qualitative "leap" into sin. Adam's leap signifies a change from one quality to another—the quality of possessing no sin to the quality of possessing sin. Kierkegaard writes that the transition from one quality to another can take place only by a "leap".
When the transition happens, one moves directly from one state to the other, never possessing both qualities.
Kierkegaard wrote, "In the Moment man becomes conscious that he is born; for his antecedent state, to which he may not cling, was one of non-being." Kierkegaard felt that a leap of faith was vital in accepting Christianity due to the

In describing the leap, Kierkegaard agreed with

.
Kierkegaard's use of the term "leap" was in response to "Lessing's Ditch" which was discussed by Lessing in his theological writings. Both Lessing and Kierkegaard discuss the
agency one might use to base one's faith upon. Lessing tried to battle rational Christianity directly and, when that failed, he battled it indirectly through what Kierkegaard called "imaginary constructions". Both were influenced by
Jean-Jacques Rousseau
Jean-Jacques Rousseau (, ; ; 28 June 1712 – 2 July 1778) was a Republic of Geneva, Genevan philosopher (''philosophes, philosophe''), writer, and composer. His political philosophy influenced the progress of the Age of Enlightenment through ...
. In 1950, philosopher Vincent Edward Smith wrote that "Lessing and Kierkegaard declare in typical fashion that there is no bridge between historical, finite knowledge and God's existence and nature."
In 1846, Kierkegaard wrote, "The leap becomes easier in the degree to which some distance intervenes between the initial position and the place where the leap takes off. And so it is also with respect to a decisive movement in the realm of the spirit. The most difficult decisive action is not that in which the individual is far removed from the decision (as when a non-Christian is about to decide to become one), but when it is as if the matter were already decided."

. The man who casts them off would make an uncertain leap over the narrowest ditch, because he is not used to such free movement. That is why there are only a few men who walk firmly, and who have emerged from nonage by cultivating their own minds."
Some theistic realms of thought do not agree with the implications that this phrase carries.

Jacobi, Hegel, and C. S. Lewis wrote about Christianity in accordance with their understanding. Kierkegaard was of the opinion that faith was unexplainable and inexplicable. The more a person tries to explain personal faith to another, the more entangled that person becomes in language and
