"Magnanimous, that is, a person of great mind, wide interests, incapable of occupying himself much about petty,  personal matters. What a pity to lose sight of such a possibility for the sake of miserable scraps of information about persons and things that have little connection with one another and little connection with ourselves!" - Charlotte Mason, Ourselves
Charlotte Mason's Ourselves, teaches the reader about they ways of the mind and the soul. In her chapter, on the desire for knowledge, she tells the reader that it is not in the shallow things that we fill our minds with, in which we experience the entirety of life. In today's culture, it is easy to allow your mind to become overcome and distracted by mindless things. We can quickly become lost in the tumultuous whirlwind of life, and are unable to grasp real knowledge of the multitude of things which are worthy of our minds. We must train ourselves to become magnanimous, and desire to have knowledge and understanding. Each person has the opportunity to decide what they wish to fill their mind with. When we fill it with petty ideas, and a load of small talk, we literally don't have the space to learn about something deeply. We have inhibited ourselves from living our lives to the fullest, and making the most of what we have.
So, what is it that makes it so much more difficult to fill our mind with large ideas, rather than things unworthy of our minds? Well, the answer is quite simple, yet, also quite disturbing as well. The small, trivial ideas which distract us and flood our thoughts are satisfying and entertaining to our minds. They quickly, build up into one large heap of ludicrous and senseless thoughts, restraining bolder ideas from entering our mind, and spark our attention.
Proverbs 4:7 says: The beginning of wisdom is this: Get wisdom, and whatever you get, get insight.
So, not only is it wise to get knowledge and fill your mind with broad ideas for your educational benefit, but for your spiritual life as well. The definition of insight is, the capacity to gain an accurate and deep intuitive understanding of a person or thing. The Bible has instructed us to gain insight. To gain knowledge. But not just any kind of knowledge. A deep knowledge. One which will not fade from you memory after an hour. No, one which will impact you for the rest of your life.
Lastly, where can you gain this knowledge? Literature is one of the greatest places to find wisdom from the authors of the past. Read several pieces from the classic authors not only for the enjoyable stories which are the vessels for the morals, but for the significant underlying themes which the author is presenting. Read their works for the wisdom which you can gain from those before you. The Bible is also undoubtedly packed full of knowledge written for our own purposes. Read chapters of the Bible, and I can assure you that you will come out with a vast expanse of knowledge and wisdom from our sagacious forefathers.
