Many religious or spiritual systems dealing with mystical experiences have a concept of gnosis. It is contrasted with rational knowledge in that it is based on a personal and usually profound experience, and is set apart from faith in that it doesn’t appeal to a sense of acceptance or emotional argument.1 Gnosis is a Greek word, γνῶσις, and while it translates as “knowledge,” it is not the only Greek word to do so. To understand what it means, it needs to be compared to two other words with similar meanings, epistēmē (ἐπιστήμη) and pistis (πίστις).
Two Types of Knowledge
While epistēmē indicates general knowledge, gnosis indicates knowledge that is personal. Epistēmē is rational knowledge formed from empirical observation or reasoning, the knowledge of a doubting mind attempting to make sense of the world around it. When knowledge falls in this category, it is of the sort that is useful and agreed-upon by everybody capable of comprehending it. Gnosis, however, is based on a personal experience. John Michael Greer writes this about gnosis:
[Gnosis] is not a matter of ordinary learning but a personal experience of spiritual truth. The Gnostic is not interested in belief; he or she wants to know, directly and personally, the spiritual realities of the cosmos.2
Gnosis and Faith
Pistis is the Greek word for faith. While gnosis is similar to faith, there is an important difference. Faith can be defined by dogma, and is primarily intellectual and emotional in character. Gnosis, on the other hand, is defined by personal insight, and is spiritual and critically experiential in character. While you might feel faith, you experience gnosis.3
Hermeticism, like Christian Gnosticism, is concerned with the experience of gnosis. Hermes Trismegistus tries to describe the gnostic experience several times throughout the Corpus Hermeticum. For example:
I have only this to tell: I see within me a formless vision born by the mercy of God. I have come out of my former self into an immortal body. I am not now what I was before. For I have been born in Nous. Such a thing is not taught, nor can it be seen by the physical body.
Corpus Hermeticum XIII.34
Personal and Experiential
To put it simply, gnosis is knowledge that comes from a direct mystical experience. It cannot be passed along to another person like knowledge of mathematics or history. It also cannot come through an emotional appeal to intellect, such as with religious conversion. Gnosis is knowledge that must be experienced to be received.
