A raised weight can produce work, but in doing so it must necessarily sink from its height, and, when it has fallen as deep as it can fall, its gravity remains as before, but it can no longer do work. Hermann von Helmholtz

The formation of scales and of the web of harmony is a product of artistic invention, and is in no way given by the natural structure or by the natural behaviour of our hearing, as used to be generally maintained hitherto. Hermann von Helmholtz

There is a kind, I might almost say, of artistic satisfaction, when we are able to survey the enormous wealth of Nature as a regularly ordered whole a kosmos, an image of the logical thought of our own mind. Hermann von Helmholtz

Not that I wish by any means to deny, that the mental life of individuals and peoples is also in conformity with law, as is the object of philosophical, philological, historical, moral, and social sciences to establish. Hermann von Helmholtz

Black is real sensation, even if it is produced by entire absence of light. The sensation of black is distinctly different from the lack of all sensations. Hermann von Helmholtz

A metaphysical conclusion is either a false conclusion or a concealed experimental conclusion. Hermann von Helmholtz

Heat can also be produced by the impact of imperfectly elastic bodies as well as by friction. This is the case, for instance, when we produce fire by striking flint against steel, or when an iron bar is worked for some time by powerful blows of the hammer Hermann von Helmholtz

Each individual fact, taken by itself, can indeed arouse our curiosity or our astonishment, or be useful to us in its practical applications. Hermann von Helmholtz

Reason we call that faculty innate in us of discovering laws and applying them with thought. Hermann von Helmholtz

I then endeavoured to show that it is more especially in the thorough conformity with law which natural phenomena and natural products exhibit, and in the comparative ease with which laws can be stated, that this difference exists. Hermann von Helmholtz

All change in nature amounts to this, that force can change its form and locality, without its quantity being changed. Hermann von Helmholtz

The universe possesses, once for all, a store of force which is not altered by any change of phenomena, can neither be increased nor diminished, and which maintains any change which takes place on it. Hermann von Helmholtz
