The structural or biogenetic relations of plant products as deduced from the recognizable architectural components of the molecules have been consistent guides in my investigations.

Most of the oils which are valued as scents are mixtures of substances; only the combined effect of these leads to the known result.

Is it philosophical, is it quite allowable, to assume without evidence from fossil plants that the family or any of the genera was once larger and wide spread? and occupied a continuous area?

To use the same words is not a sufficient guarantee of understanding; one must use the same words for the same genus of inward experience; ultimately one must have one's experiences in common.

Identical twins are endemically alike in many ways.

And, you know, the fact is, if you believe in evolution, we all have a common ancestor, and we all have a common ancestry with the plant in the lobby. This is what evolution tells us. And, it's true. It's kind of unbelievable.

I've always loved to combine different scents to come up with my own unique thing.

As soon as science has solved one problem, new ones arise. This is the essence of science, and it applies, of course, also to the field of essential oils.

Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms.
