How might an appreciative conceptual inquiry be practiced in a field such as organisational change? Two approaches give some direction for this type of inquiry: multiparadigm inquiry and integral metatheory. Inquiring appreciatively into conceptual diversity means that the contributions of multiple theories are acknowledged and included within our explanations and sense-making endeavours. Multiparadigm inquiry and integral methodological pluralism are examples of an appreciative approach to the unity of theory and action. Theory building is based on a shared motive for uncovering mystery, for enriching experience and for disclosing new visions.
