FRIEDRICH FROEBEL.

"The correct perception is a preparation for correct knowing and
thinking."
FRIEDRICH FROEBEL.

"No new subject of instruction should come to the scholar, of which he
does not at least conjecture that it is grounded in the former
subject, and how it is so grounded as its application shows, and
concerning which he does not, however dimly, feel it to be a need of
the human spirit."
FRIEDRICH FROEBEL.

"The sequences which the child builds, as well as the sequence of the
kindergarten gifts, point on the one hand to physical evolution,
wherein each form 'remembers the next inferior and predicts the next
higher,' and on the other to the process of historic development,
which magnifies the present by linking with it the past and the
future."
SUSAN E. BLOW.

"Let us educate the senses, train the faculty of speech, the art of
receiving, storing, and expressing impressions, which is the natural
gift of infants, and we shall not need books to fill up the emptiness
of our teaching until the child is at least seven years old."
E. SEGUIN.

"As soon as we, young or old, have taken to the habit of asking the
book for what it is in our power to learn from personal observation,
we dismiss our organs of perception and comprehension from their
righteous charge, and cover the emptiness of our own minds with the
patchwork of others."
E. SEGUIN.

"Natural geometry (taking the word in its limited sense of study of
form in space) is the object of a desire which generally precedes the
artificial curiosity for the meaning of letters."
E. SEGUIN.

"Without an accurate acquaintance with the visible and tangible
properties of things, our conceptions must be erroneous, our
inferences fallacious, and our operations unsuccessful."
HERBERT SPENCER.

"The truths of number, of form, of relationship in position, were all
originally drawn from objects; and to present these truths to the
child in the concrete is to let him learn them as the race learned
them."
