You could find a few on general quote collection sites, a smattering on other websites, and some in books. But there was no repository that brought them all together. I finally decided to create such a collection myself, and below you will find the result.
When it comes to quotes about manhood, you could conceivably include ones that touch on the different qualities of manhood, i.e., quotes on courage, strength, resolution, etc. But what we have aimed to do here is to limit the collection to quotes that reference manhood itself. We hope you enjoy the quotes and perhaps find a few that will illuminate the meaning of manliness and encourage you to embody it.
"To have done no man a wrong…to walk and live, unseduced, within arm's length of what is not your own, with nothing between your desire and its gratification but the invisible law of rectitude—this is to be a man." –Horace Mann
"You have to be a man before you can be a gentleman." –John Wayne (McLintock!)
