Organon §18

The totality of symptoms and circumstances in each individual case of disease must be the sole indicator in choosing a remedy.

It is an undeniable truth that nothing can, by any means, be discovered in diseases whereby they could express their need for aid besides the totality of symptoms, with consideration for the accompanying circumstances (§5). Therefore, it follows incontestably that the complex of all the symptoms and circumstances perceived in each individual case of disease must be the only indicator, the only reference in choosing a remedy.
