All Faculties to Be Cultivated—If certain faculties are used to the neglect of others, the design of God is not fully carried out in us, for all the faculties have a bearing and are dependent, in a great measure, upon one another. One cannot be effectually used without the operation of all, that the balance may be carefully preserved. If all the attention and strength are given to one, while others lie dormant, the development is strong in that one and will lead to extremes, because all the powers have not been cultivated. Some minds are dwarfed and not properly balanced. All minds are not naturally constituted alike. We have varied minds; some are strong upon certain points and very weak upon others. These deficiencies, so apparent, need not and should not exist. (1MCP 50.1) MC VC

If those who possess them would strengthen the weak points in their character by cultivation and exercise, they would become strong.—Testimonies for the Church 3:33 (1872). (1MCP 50.2) MC VC

Call All Powers of Mind Into Use—All the powers of the mind should be called into use and developed in order for men and women to have well-balanced minds. The world is full of one-sided men and women who have become such because one set of their faculties was cultivated while others were dwarfed from inaction. (1MCP 50.3) MC VC

The education of most youth is a failure. They overstudy, while they neglect that which pertains to practical business life. Men and women become parents without considering their responsibilities, and their offspring sink lower in the scale of human deficiency than they themselves. Thus the race is fast degenerating. (1MCP 50.4) MC VC

The constant application to study, as the schools are now conducted [1872], is unfitting youth for practical life. The human mind will have action. If it is not active in the right direction, it will be active in the wrong. In order to preserve the balance of the mind, labor and study should be united in the schools.—Testimonies for the Church 3:152, 153 (1872). (1MCP 50.5) MC VC
