A Quote by Otto Wallach
As soon as chemists have a definite conception of the internal structure of the molecule of an organic compound, they are able to tackle the task of producing these substances by artificial methods, i.e. by synthesis, as we call it.

As soon as we can wrest from Nature the secret of the internal structure of the compounds produced by her, chemical science can then even surpass Nature by producing compounds as variations of the natural ones, which the living cell is unable to construct.
Synthetic or inorganic substances do not contain any 'life force'; they are not dynamic. Everything is made of chemicals, but organic substances like essential oils have a structure which only mother nature can put together. They have a life force, an additional impulse which can only be found in living things.
The chemists work with inaccurate and poor measuring services, but they employ very good materials. The physicists, on the other hand, use excellent methods and accurate instruments, but they apply these to very inferior materials. The physical chemists combine both these characteristics in that they apply imprecise methods to impure materials.
The mineral kingdom consists of the fossil substances found in the earth. These are either entirely destitute of organic structure, or, having once possessed it, possess it no longer: such are the petrefactions.
It is fortunate that molecular synthesis also serves the utilitarian function of producing quantities of rare or novel substances which satisfy human needs, especially with regard to health, and the scientific function of stimulating research and education throughout the whole discipline of chemistry.
The real, then, is that which, sooner or later, information and reasoning would finally result in, and which is therefore independent of the vagaries of me and you. Thus, the very origin of the conception of reality shows that this conception essentially involves the notion of a COMMUNITY, without definite limits, and capable of a definite increase of knowledge.
This investigation has yielded an unanticipated result that reaction of cyanic acid with ammonia gives urea, a noteworthy result in as much as it provides an example of the artificial production of an organic, indeed a so-called animal, substance from inorganic substances.
It does not seem, however, that organic chemists were much worried about barriers to rotation in organic molecules in general at that time because there was no technique available to demonstrate the phenomenon experimentally.
During our stay in London for the first time I was able to establish personal contact with some of the organic chemists, whose work I knew and admired from the literature. I found them most gracious and helpful.
Since it is necessary for specific ideas to have definite and consequently as far as possible selected terms, I have proposed to call substances of similar composition and dissimilar properties isomeric, from the Greek ???????? (composed of equal parts).
The most practical of all methods for controlling the mind is the habit of keeping it busy with a definite purpose, backed by a definite plan.
A single kind of red cell is supposed to have an enormous number of different substances on it, and in the same way there are substances in the serum to react with many different animal cells. In addition, the substances which match each kind of cell are different in each kind of serum. The number of hypothetical different substances postulated makes this conception so uneconomical that the question must be asked whether it is the only one possible. ... We ourselves hold that another, simpler, explanation is possible.
It must be admitted that the conception of virtue cannot be separated from the conception of happiness-producing conduct.
In fact people do not know enough about themselves and what is good for them to form a sufficiently definite conception of the general happiness (or whatever the end is) to establish definite rules for its pursuit.
All methods are sacred if they are internally necessary. All methods are sins if they are not justified by internal necessity.
I have always had the feeling that organic chemistry is a very peculiar science, that organic chemists are unlike other men, and there are few occupations that give more satisfactions [sic] than masterly experimentation along the old lines of this highly specialised science.
