Various types of magic can also be categorized by the techniques involved in their operation. For example, there are contagious magic and sympathetic magic, one or both of which may be employed in any magical work. Contagious magic involves the use of physical ingredients which were once in contact with the person or thing the practitioner intends to influence. Sympathetic magic involves the use of images or physical objects which in some way resemble the person or thing one hopes to influence; voodoo dolls are an example.
Other common categories given to magic include High and Low Magic. Manifest and Subtle magic typically refers to magic of legend rather than what many individuals who practice the occult claim to use as magic, where Manifest magic is magic that immediately appears with a result, and Subtle magic being magic that gradually and intangibly alters the world.
Magic and study of occult arts successfully survived Renaissance and entered the Baroque era. And even more. ”study of the occult arts remained intellectually respectable well into the seventeenth century”. It only gradually divides into the modern categories of natural science versus occultism or superstition. My web research shows, that brilliant Age of Reason was on the rise in the seventeenth century, while belief in witchcraft and sorcery, and consequently the irrational surge of Early Modern witch trials, receded. This process only completed at the end of the Baroque period, somewhere around 1730s.
Contemporary scientists still met resistance, though. Christian Thomasius encountered fierce opposition as he argued in his 1701 Dissertatio de crimine magiae that it was meaningless to make dealing with the devil a criminal offence, since it was impossible to really commit the crime in the first place. In Britain, the Witchcraft Act of 1735 established that people could not be punished for consorting with spirits, while would-be magicians pretending to be able to invoke spirits could still be fined as con artists.
Several decades later, from 1756 to 1781, Jacob Philadelphia performed feats of magic, sometimes under the guise of scientific exhibitions, throughout Europe and Russia. Baron Carl Reichenbach’s experiments with his Odic force appeared to be an attempt to bridge the gap between magic and science.
