Courage is a mean with regard to fear and confidence.
Aristotle, Nicomachean Ethics|Nicomachean Ethics 3.6 (1094 A.D.)
Cowards die many times before their deaths;The valiant never taste of death but once.
William Shakespeare, Julius Caesar, Act II, sc. ii (1599)
I dare do all that may become a man;Who dares do more is none.
William Shakespeare, Macbeth, Act I, sc. vii (c. 1605)
Complete courage and absolute cowardice are extremes that very few men fall into. The vast middle space contains all the intermediate kinds and degrees of courage; and these differ as much from one another as men’s faces or their humors do.
François de La Rochefoucauld, Moral Maxims and Reflections, no. 215 (1665-1678)
Perfect courage is to do without witnesses what one would be capable of doing with the world looking on.
François de La Rochefoucauld, Moral Maxims and Reflections, no. 216
Courage, of all national qualities, is the most precarious; because it is exerted only at intervals, and by a few in every nation; whereas industry, knowledge, civility, may be of constant and universal use, and for several ages, may become habitual to the whole people.
David Hume, Of National Characters, part I, essay XXI (1758)

Courage is a quality so necessary for maintaining virtue, that it is always respected, even when it is associated with vice.
Samuel Johnson, Quoted in James Boswell, Life of Samuel Johnson, June 11, 1784 (1791)
It requires courage not to surrender oneself to the ingenious or compassionate counsels of despair that would induce a man to eliminate himself from the ranks of the living; but it does not follow from this that every huckster who is fattened and nourished in self-confidence has more courage than the man who yielded to despair.
Soren Kierkegaard, “Irony as a Mastered Moment: The Truth of Irony,” pt. 2, The Concept of Irony (1841)
The French courage proceeds from vanity—the German from phlegm—the Turkish from fanaticism & opium—the Spanish from pride—the English from coolness—the Dutch from obstinacy—the Russian from insensibility—but the Italian from anger.
George Gordon Noel Byron(1788–1824), British poet. in a letter to his publisher John Murray. (1820)

As a strength in psychology
From the end of the twentieth century, courage has been a concept generating interest in the field of psychology. In 2004, Christopher Peterson and
Martin SeligmanMartin E. P. "Marty" Seligman is an American psychologist, educator, and author of self-help books. His theory of "learned helplessness" is widely respected among scientific psychologists....
’s book, Character Strengths and Virtues proposed a uniform way of classifying positive traits that highlight the elements of humanity that uplift humanity, Courage being among the key virtues. In addition, Seligman and Peterson founded the Virtues in Action (VIA) Institute and created the VIA survey which hope to bring this uniform categorization of human strengths to the masses. The VIA

It was created by Christopher Peterson and Martin Seligman, well-known researchers in the field of positive psychology, in order to operationalize...
in six, broad categories: Wisdom and Knowledge, Courage, Humanity, Justice, Temperance, Transcendence. Courage is broken down into four main subcategories: Bravery, Perseverance, Honesty, and Zest.
Bravery
Bravery is the subcategory most people generally associate with Courage. It is defined as “the ability to stand up for what is right in difficult situations.” As opposed to less sophisticated definitions that simply categorize bravery as fearlessness or acting when an observer would be afraid. There are several forms of this bravery. Physical bravery involves acting in spite of possible harm to one’s body. Moral bravery involves acting in a way that enhances what one believes to be good in spite of social disapproval and possible backlash. A third, theoretically newer, definition of bravery is psychological bravery which involves things such as overcoming one’s own addictive habits, irrational anxieties, and harmful dependent relationships. Psychological bravery means acting against one’s own natural inclinations and facing fears which might not have any societal moral implications. Bravery works well as a virtue in the VIA classification system because it is highly regarded across cultures and has obvious benefits for those surrounded by brave people. Possible problems with viewing bravery as a classifiable human strength is that it could be argued that bravery is not trait-like since it only comes out under certain circumstances. The counterargument to this claim is that bravery is trait-like in the same way creativity is considered a trait; both appear only in certain situations. The VIA claims that it is a positive psychological trait that can be found and cultivated in certain individuals.
Perseverance
Perseverance falls under the larger category of courage because it often involves continuing along a path in the midst of and after having faced opposition and perhaps failure. Perseverance involves the ability to seek a goal in spite of obstacles and has been shown in human and animal studies to be a lasting trait with individual differences. In order to persevere at a task, a person must be able to suppress desires to give up and pursue an easier task, a metacognitive understanding that the ends justify the persevering means. But beyond meta cognition, a person high in perseverance is able to overcome low self-esteem and estimations that one cannot do the task as well as discouragement from peers and the desire to present oneself well. As a categorical psychological strength, perseverance is regarded highly by society as opposed to laziness. However, its one weakness as an entry on the VIA as noted by Peterson and Seligman is that it may not be discernible from other human strengths and virtues. It especially can be seen as overlapping with self-control. However Peterson and Seligman maintain its distinctiveness, pointing out that perseverance “is explicitly shown across time, whereas control and regulation of oneself have a more here-and-now flavor”. More research needs to be done in this area to empirically show that perseverance belongs in its own distinct category.
Honesty
As defined by positive psychologists, honesty and authenticity as a subset of courage means more than simply telling the truth. It involves integrity in all areas of one’s life and the ability to be true to oneself and one’s role in the world across circumstances. Though perhaps one would not immediately associate honesty with courage, there are obvious situations in life where to be honest and authentic requires a great deal of strength in the midst of fear. The positive view societies have of honesty can be seen from the fact that it is something people try to develop in young children and adolescents. While all people seem to grow in their understanding of the moral importance of honest and integrity as they grow older, there are certain individuals who seem to especially excel in this human strength. This trait is important in many areas of life, so much so that many measurements have been developed in an effort to identify especially honest individuals. These measurements test both overt honesty, the thoughts one has about blatant dishonesty such as stealing, and covert honesty, which is very similar to conscientiousness and dependability. Of all the subcategories under courage in the VIA, Honesty shows the most promise as a distinct, well defined area of classification.
Zest
Of the four categories involved in courage, zest or vitality, is the one that has the most weaknesses as a classification. It is defined as, “feeling alive, being full of zest, and displaying enthusiasm for any and all activities”. This is a category that is influenced not only by subjective psychological factors, but also objective factors affecting one’s physical well-being such as chronic pain. The reason Peterson and Seligman group Zest together with other courageous virtues is that Zest most often comes forth as a character strength in the midst of trying circumstances. For example, it has been shown that people’s subjective perception of their situation when faced with chronic pain, judging their perceived ability to handle the situation and their general positivity, is able to influence their well-being. This zest can be shown to be trait-like across situations.
