Hide [and Seek], or: who is kickin'?
Art, more specifically abstract art, invites to find things: the unknown, the subtly sensed, the pre-known. Finding means to be open for new insights, which then will - quite literally - broaden one's horizon. The inner attitude required hereby is an openness towards the new and unknown, an accepting, investigative curiosity.
It is specifically this attitude which may cause some spectators less familiar with the concepts of contemporary art to feel insecure and thus instead of "finding" rather opt for an attitude of "searching", specifically searching for those elements they already know. However, like that they will just once more reconfirm their own concepts about themselves and the world. All investigative and on the long run enriching curiosity vanishes away, and without it the spectator seeking in vain the familiar in an abstract work of art will walk away disappointedly.
