The Triune God of the Bible has declared that His thoughts are not our thoughts, and that to be able to live in accord with the reality of the universe that He has created, we need to think His thoughts after Him. This highlights a tension between memory and imagination. God’s complaint is that “The Lord saw the wickedness of man was great in the earth, and that every intention of the thoughts of his heart was only evil continually” (Genesis 6:5) … “for the intention of man’s heart is evil from his youth” (Genesis 8:21).
Rushdoony (2008), commenting on the Songs of Moses (Exodus 15, Deuteronomy 32 and Psalm 90), writes:
There is a contrast in our text between imagination and memory. Men must not trust in the imagination, because it reflects their fallen history. God’s appointed servants must discipline and teach, so that man’s memory is mindful of God’s works, covenant, law, grace and mercy. The issue is between educational approaches stressing memory versus those stressing imagination. To stress imagination means to believe in the child’s or person’s creative powers, whereas to emphasize memory is to maintain that the future must be built on the knowledge of the past under God. Knowledge is not manufactured anew with every generation. It is a growing structure based on biblical premises, whereas modern education is deliberately rootless and barren (Rushdoony, 2008, p. 491).
There are windows of opportunity in a child’s life, where memory and repetition are fun. If you miss those windows, then it is harder to develop a discipline of memorization later in life. Home-based education should include sessions of memorization, of things like: Books of the Bible, names of the Patriarchs and the Apostles, significant historical events, and their dates (Bishop Ussher’s (2003 [1658]) Annals of the World is helpful with this) — i.e Creation, Deluge, Tower of Babel, etc. — Creeds and Catechisms, countries around the world and their capitals, local mountain ranges and rivers, and many other things.
An education is much more than memorization, but at the same time must include memorization.
