d must be given a knowledge of science and
philosophy--that is, as much as may be deemed necessary. All cannot be
scientists and philosophers, but each should be educated according to his
needs and deserts.

Baha'u'llah teaches that the world of humanity is in need of the breath of
the Holy Spirit, for in spiritual quickening and enlightenment true
oneness is attained with God and man. The Most Great Peace cannot be
assured through racial force and effort; it cannot be established by
patriotic devotion and sacrifice; for nations differ widely and local
patriotism has limitations. Furthermore, it is evident that political
power and diplomatic ability are not conducive to universal agreement, for
the interests of governments are varied and selfish; nor will
international harmony and reconciliation be an outcome of human opinions
concentrated upon it, for opinions are faulty and intrinsically diverse.
Universal peace is an impossibility through human and material agencies;
it must be through spiritual power. There is need of a universal impelling
force which will establish the oneness of humanity and destroy the
foundations of war and strife. None other than the divine power can do
this; therefore, it will be accomplished through the breath of the Holy
Spirit.

No matter how far the material world advances, it cannot establish the
happiness of mankind. Only when material and spiritual civilization are
linked and coordinated will happiness be assured. Then material
civilization will not contribute its energies to the forces of evil in
destroying the oneness of humanity, for in material civilization good and
evil advance together and maintain the same pace. For example, consider
the material progress of man in the last decade. Schools and colleges,
hospitals, philanthropic institutions, scientific academies and temples of
philosophy have been founded, but hand in hand with these evidences of
development, the invention and production of means and weapons for human
destruction have correspondingly increased. In early days the weapon of
war was the sword; now it is the magazine rifle. Among the ancients, men
fought with javelins and daggers; now they employ shells and bombs.
Dreadnoughts are built, torpedoes invented, and every few days new
ammunition is forthcoming.

All this is the outcome of material civilization; therefore, although
material advancement furthers good purposes in life, at the same time it
serves evil ends
